I am having a problem with my gtk program doing a seg fault after
running for a long period of time. My application redraws the screen
with quite a high frequency. I decided to to creating a tiny test
program that simply sets icons on a toolbar over and over to see if I
could replicate the problem my application is having. After almost 3
days my test gtk program segfault'ed in the same manner. It does not
seem to be a memory leak as the memory usage of the program did not grow
over time.
I am using Fedora Core 6 and all the standard GTK, Glib libraries that
it contained, i.e. GTK 2.10.8
When I tried this on a PC running Fedora8 and a new gtk library I did
not see the issue but perhaps it just takes longer before it would
crash.
Here is the backtrace:
Core was generated by `./gtktest'.
Program terminated with signal 11, Segmentation fault.

Here is the code for my test program.. I used glade to create the
window and a toolbar with three buttons on it. I can provide the glade
file if anyone wants it.
