You can run gtk-gnutella in gdb. Recompile it with
debugging symbols if necessary. Grep in the source
code for the assert that is failing, then set a
breakpoint just before or at that line. Then
in gdb, execute the 'bt' (backtrace) command
in the instance of a condition that will yield
an assert failure.
You can tell if there will be an assert failure
by using the 'print' command in gdb to display
the values of the different variables.
If it is memory corruption of the stack, you
should be able to see that in the debugger's
stack trace (backtrace). You can analyze
the frames to find the exact point of the
corruption. If it is an uninit'd variable,
you should be able to determine that from
the print command in the debugger.
