Re: [Ekiga-devel-list] win32 issues

[Michael Rickmann <mrickma gwdg de>]

Ok I have submitted the two bug reports 
https://sourceforge.net/tracker/?func=detail&aid=2728003&group_id=204472&atid=989748
https://sourceforge.net/tracker/?func=detail&aid=2728037&group_id=204472&atid=989748

Another Win32 issue, the "crash on exit" one: I have been fighting to
obtain a debug built of ekiga which allows gdb to backtrace across
different dlls. For others who try the same: in the win32 Makefile
autogen.sh with --enable-opal-debug instead of --enable-debug and
use -gstabs instead of -g as the debugging flag. Attached gdb backtrace
was produced on an XP home machine using the gdb contained in
https://sourceforge.net/project/downloading.php?group_id=204414&use_mirror=switch&filename=gdbserver-6.8-002-20090131.exe&a=88862589
To me the underlying bug appears obscure. Apparenly, it happens when the
sigc++ objects for the address book are destroyed. Can anyone suggest a
strategy how to approach this crash?
