Title: [Ethereal-dev] Access violation failure on exit with VC++ Debugger?

I described this bug yesterday and submitted a patch fixing it.

 

Here's the explanation I sent:

 

A system exit caused Ethereal to use a dangling pointer leading to an
app crash. I.E. a system exit caused do_quit() to return FALSE. Hence,
the top_level->window was deleted but not necessarily set to NULL. With
this patch, do_quit always returns TRUE and it's therefore safe to take
geometry's info after gtk_main (the system destroys Windows). In
addition, I'm not sure it is recommended to test the window pointer of
the widget. I prefer to use the GTK_WIDGET_NO_WINDOW() macro.

Objet: [Ethereal-dev] Access violation failure on exit with VC++ Debugger?

Wondering about the following behaviour:
When debugging with MS Visual C++6, i get an access violation failure on
exit:
gtk/main.c (2443): in function main: gdk_window_get_size(top_level->window,
&top_width, &top_height);
top_level->window points to somewhere in deep space.

happens only when debugging ("Go" command from IDE).

(Ethereal 0.9.15, GTK+1.3.0, GLib 1.3.2, Windows 2000 SP4)
any ideas?
Lars
