  gnomemm | libgdamm | Ver: unspecified

           Summary: Inconsistent Gnome::Gda::Value semantics
           Product: gnomemm
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: libgdamm
        AssignedTo: gtkmm-forge lists sourceforge net
        ReportedBy: armin arbur net
         QAContact: gtkmm-forge lists sourceforge net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


Gnome::Gda::Value has different set() overloads, of which most do just
g_value_set_*. g_value_set_* does not allow changing the value's type, so
calling set("foo") on an uninitialized value (or one that holds another type
than G_TYPE_STRING) raises an error.

Other overloads use a gda_value_set_* function which does first unset the value
and initialize it with the correct type again. Therefore, calling the set()
overload that takes a GdaTime works on an uninitialized value. This is
inconsistent and might confuse people.

I think this is easy to fix once we agree on what to do in all cases. Allowing
the Value to change its type during its lifetime is preferable, I guess, so
adding g_value_unset()/g_value_init() calls to the set() functions that use
g_value_set*  might be enough.

Using valgrind I found that function Gtk::TreeView::get_cursor() has memory
leak for GtkTreePath pointer.

------- Comment #1 from Bryan Silverthorn  2007-03-12 20:22 UTC -------
I see memory corruption in a real application due to this issue, with valgrind
catching invalid writes at the conn_node->install() line. I can't share the
application source, unfortunately, but I can test any relevant glibmm patches.

Moving the install(source) call to a spot before g_source_attach() does appear
to eliminate at least that source of memory corruption. Some thread-related
corruption issue still remains, but it is much harder to trigger, and I haven't
been able to reproduce it under valgrind.

  gtkmm | build | Ver: 2.10.x

           Summary: ntstatus 0xc0150002
           Product: gtkmm
           Version: 2.10.x
          Platform: Other
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: build
        AssignedTo: gtkmm-forge lists sourceforge net
        ReportedBy: jvd tja lt
         QAContact: gtkmm-forge lists sourceforge net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


OS: Win XP
Compiler: vc++ 8.0 (14.0.50727.42); Visual Studio Express 2005
Gtk+ win32 build: 2.10.7

Compiling with 2.10.8-1 (with 2.10.7-1, too) devel build, all gtkmm executables
(in debug mode; runtime -- MT Debug DLL) produce the following error:
LDR: LdrpWalkImportDescriptor() failed to probe
C:\PROGRA~1\GTK\bin\gtkmm-2.4d.dll for its manifest, ntstatus 0xc0150002

In release mode the error is quite the same (runtime -- MT DLL):
LDR: LdrpWalkImportDescriptor() failed to probe
C:\PROGRA~1\GTK\bin\gtkmm-2.4.dll for its manifest, ntstatus 0xc0150002

The same is reproducible with various platform sdks (SP1, R2).

The problem is rectifiable by recompiling glibmm and gtkmm packages.
