My Gtk Application most of the times dies giving a segmentation fault at gtk_widget_show(window2).

Debugger gdb, shows the same error as
gtk_window_show() at eval.c: 41.
41 eval.c no such file or directory.

If not at this statement, some other times gbd stops at end of a function showing error at gtk_marshal_NONE_NONE().

Anyone, please lemme know a way to avoid this segmentation fault.

Thanks,
Jagan.

PS:
1. I tried "myapplication --sync" for any error logging, this doesnt help me.
2. Also did MALLOC_CHECK_=2 for that environment variable, havent got any more informatio.

It might help if you posted some of your source code, especially line 41 of eval.c and the code surrounding it
