+Summary: Pango::Context::set_font_description causes app to abort when layout is drawn
+
+if i try to change the font using a pango context, the app aborts when i
+try to draw the pango layout.
+
+here is some example code:
+
+Gtk::Window* pWin = NULL;  // excuse the global...it's just a test app
+typedef Glib::ArrayHandle< Glib::RefPtr<Pango::FontFamily> > tFontList;
+
+bool
+draw(GdkEventExpose* pEvent)
+{
+
+    // -------------------------------------------------------------------
+    // this is the only way that works and allows you to change the font:
+    // -------------------------------------------------------------------
+    //                                                                    
+    // Glib::RefPtr<Pango::Layout> pLayout = 
+    //     pWin->create_pango_layout("Pango Test Application");
+    // Pango::FontDescription font("fixed");
+    // pLayout->set_font_description(font); 
+
+    // ------------------------------------------------------------------
+    // broken examples below:
+    // ------------------------------------------------------------------
+
+    // this never works
+    //
+//  Glib::RefPtr<Pango::Context> pContext = Pango::Context::create();
+
+    // both of these work as long as i don't call set_font_description below
+    //
+//  Glib::RefPtr<Pango::Context> pContext = pWin->get_pango_context();
+    Glib::RefPtr<Pango::Context> pContext = pWin->create_pango_context();
+
+    // this displays a list of all my fonts, including "fixed"
+    //
+    tFontList pArray = pContext->list_families();
+    for (tFontList::const_iterator itr = pArray.begin();
+         itr != pArray.end(); ++itr) {
+         Glib::RefPtr<Pango::FontFamily> pFamily = *itr;
+         std::cout << pFamily->get_name() << std::endl;
+    }
+
+    // calling set_font_description causes the app to abort when     
+    // draw_layout
+    // is called, saying it can't find font "fixed" or any fallbacks,
+    // even though "fixed" is listed by the above code.  i've tried it
+    // with many other font names and it's always the same result.
+    //
+    Pango::FontDescription font("fixed");        
+    pContext->set_font_description(font);
+
+    Glib::RefPtr<Pango::Layout> pLayout = Pango::Layout::create(pContext);
+    pLayout->set_text("Pango Test Application");
+
+    Glib::RefPtr<Gdk::GC> gc = pWin->get_style()->get_black_gc();
+    pWin->get_window()->draw_layout(gc, 10, 10, pLayout);
+}
+
+int
+main(int argc, char* argv[])
+{
+	Gtk::Main kit(argc, argv);
+
+	pWin = new Gtk::Window(Gtk::WINDOW_TOPLEVEL);
+	
+	pWin->set_default_size(500, 100);
+
+	pWin->signal_expose_event().connect(SigC::slot(draw));
+	
+	pWin->show_all();
+
+	
+	kit.run();

+Summary: pangomm has some bugs and incomplete documentation
+
+Sorry, for the general summary. Straight forwardness from now on: here
+comes the ChangeLog :-)
+
+* api_status.txt: Reflect recent API additions to pangomm.
+* TODO: copy the TODO's from this ChangeLog.
+* tools/pm/DocParser.pm: Comment out conditional if-clause
+around conversion from C documentation to C++. It prevented
+conversion of the documentation in *_docs_override.xml which
+currently is in the same style as *_docs.xml and lead to
+mistakes in our overridden gtk documentation.
+* pangomm/src/attributes.hg: Make Attr* default constructors
+protected. They don't produce legal attribute objects.
+Attribute::Attribute() produces an object with gobject_==0.
+This is handled as if it were an attribute of type ATTR_INVALID
+and allows wrapping of NULL return values from pango c functions.
+* pangomm/src/attriter.ccg: Correct possible bug in
+AttrIter::get_font(). (Taken a hint in pagno c ref doc serious :)
+* pangomm/src/attrlist.hg: Add default argument for: explicit
+AttrList::AttrList(const Glib::ustring&, gunichar accel_marker=0).
+* pangomm/src/context.hg:
+ - Remove _WRAP_CREATE(). It can't
+  possibly initialize the Pango::Context object correctly because
+  some PangoFontMap is needed from a pango backend.
+- Add default argument Language() for the language parameter of
+  Context::get_metrics. TODO: Use a function overload instead.
+* pangomm/src/coverage.{hg,ccg}: - Change Coverage::to_bytes()
+to return a Glib::ArrayHandle<unsigned char> instead of an
+guchar* array that needs to be freed with g_free() by hand.
+- Remove Coverage::copy(). The pango docs state that is is
+  superfluous.
+* pangomm/src/font.hg:
+- Add default argument Language() for the
+  language parameter of Font::get_metrics().
+  TODO: Use a function overload instead.
+- TODO: Ask list whether we really need
+  Font::get_glyph_extents_{ink,logical}_rect_only().
+* pangomm/src/fontdescription.hg: TODO: Investigate the following:
+FontDescription::{set_family_static,merge_static} look as
+if they could lead to undefined results and corrupted data.
+* pangomm/src/glyph.{hg,ccg}:
+- Add Glib::wrap(PangoGlyphInfo*). I forget it last time.
+- Comment out set_* in GlyphInfo and GlyphGeometry. They don't make sense
+  as GlyphInfo and GlyphGeometry are merely output classes to the user.
+* pangomm/src/glyphstring.{hg,ccg}:
+- Add GlyphString::GlyphString(const Glib::ustring&, const Analysis&).
+  This wraps pango_shape which didn't do up to now.
+- Make GlyphString::get_logical_widths, GlyphString::index_to_x and
+  GlyphString::x_to_index calculate take the size of the passed text
+  parameter from the Glib::ustring itself rather than demanding an
+  extra argument. GlyphString::get_logical_width now allocaltes an
+  array to store the results rather than expecting the user to do this.
+* pangomm/src/item.{hg,ccg}: Add Item::get_segment() and Item::shape().
+  The former computes the text segment that is covered by the item
+  (convenience one-line-function not available in pango), the latter
+  wraps the new GlyphString constructor and thus pango_shape().
+* pangomm/src/language.{hg,ccg}:
+- Add Language::Language() that constructs an object with gobject_==0.
+- Adapt Language::get_string to allow for objects with gobjct_==0.
+- TODO: Change const char* into std::string.
+* pangomm/src/layout.ccg: Bug fix: use text.bytes() instead of ext.size().
+* pangomm/src/layout.hg: Bug fix: use refreturn parameter of _WRAP_METHOD
+for Layout::get_context() and Layout::get_line().
+* pangomm/src/layoutiter.hg: Bug fix: use refreturn parameter of
+_WRAP_METHOD for LayoutIter::get_line().
+* pangomm/src/{*.hg,*.ccg}: Add lots of documentation.
+I hope that some things I had to learn the hard way become clear
+in the class description of Pango::Context.

 Thanks for the report.
 
 This _might_ be related to this gcc 2.9* compiler bug:
 http://bugzilla.gnome.org/show_bug.cgi?id=78578
 
 Can you find a similar workaround for these classes?

+------- Additional Comments From indigo sempiternity org  2002-09-04 22:45 -------
+From what I've read about the possible compiler bug, it seems quite
+likely and matches up quite nicely to what I've observed in gdb. I
+have no way to verify, however. I've exchanged some emails with ERDI
+"cactus" Gergo about this bug, and he was unable to reproduce it. The
+other guy I'm working on the project with could reproduce the bug, and
+I've sent inqueries as to the compilers used to each. If anyone with
+gcc 3.2 or so could please test, we might get some idea of what's
+going on.
+
+As for a fix for the problem, I can't think of any workaround. Damn
+gcc sucks... Perhaps if someone could point me towards the specific
+dynamic_cast that's causing the problem I could rewrite it with static
+casts? I can't really require gcc 3.2, and I can't avoid inheriting
+without major troubles, so any ideas would be much apreciated :)
