  gtkmm | general | Ver: 2.8.x

           Summary: The application crashes with SIGSEGV in ComboBoxText
                    destructor
           Product: gtkmm
           Version: 2.8.x
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: general
        AssignedTo: gtkmm-forge lists sourceforge net
        ReportedBy: slava fizlesh org ru
         QAContact: gtkmm-forge lists sourceforge net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


Steps to reproduce:

I have written the small program that demonstrates this crash. I'll attach the
source to this bug.

1. Compile the program:
g++ `pkg-config --cflags --libs gtkmm-2.4` -ggdb a.cpp

2. Run it

3. On the first page of Gtk::Notebook (which is currently opened) click the
ComboBoxText, and select the sole item

4. Switch to the second page. The ComboBoxText on it will have focus.

5. Close the window. The application will crash with the following message:
(a.out:9835): GLib-GObject-CRITICAL **: g_object_ref: assertion
`object->ref_count > 0' failed
Segmentation fault (core dumped)

Stack trace:
If application is run in regular manner, the stack trace doesn't show anything
useful (it appears that at the moment of segfault the stack frame information
is inconsistent):

#0  0xb75a462a in ?? () from /usr/lib/libgobject-2.0.so.0

#3  0x00008002 in ?? ()
#4  0x00008002 in ?? ()
#5  0x00000000 in ?? ()

If I run the application with G_DEBUG=fatal_criticals, the stack trace is more
informative:

#0  0xb7fbf410 in __kernel_vsyscall ()
#1  0xb73cd601 in raise () from /lib/libc.so.6

#20 0x00000000 in ?? ()


Other information:
I am using Gentoo with gtk-2.10.9 and gtkmm-2.8.3. The same bug was observed on
Suse 10.2 with gtk-2.10.6 and gtkmm-2.10.2.

I have also observed that if you move focus on the second page away from
ComboBoxText, the crash won't happen.

There was a change in the GNU m4 --version output in version 1.4.3. 
scripts/macros.m4 expects "GNU m4 x.y.z" but current GNU m4 returns "GNU M4
x.y.z" -- the difference being the capitalized M in M4.  This causes
AL_PROG_GNU_M4 to return no with the newer versions.

This affects scripts/macros.m4 in _ALL_ of the C++ bindings.

------- Comment #4 from Murray Cumming  2007-03-30 10:24 UTC -------
Here's an example of where the gtkmm connect-after-by-default behaviour is
desirable (as well as intuitively expected) for a non-X-event-signal example:
  In the signal handler for the GtkNotebook::switch-page signal,
gtk_notebook_get_current_page() will return the incorrect value when using
g_signal_connect(), but will return the correct value (the same as the
handler's page_num parameter) when using g_signal_connect_after(). Presumably
the default signal handler does important work, which we want the benefit of in
our own signal handler.

Port to libgda3

This is a patch that merges the GLOM_LIBGDA3 branch to trunk. It makes glom use
the new libgda3 API and pygda3. Issues while porting to the new API are noted
in the TODO file, especially the database creation still needs a better
solution. Make sure you have the latest pygda and libgdamm from SVN.
