The following example shows how it can be used together with
the g_log() functions.

If "Exit" is selected, the application terminates with a call
to _exit(0).
If "Stack" trace is selected, g_on_error_stack_trace() is called.
This invokes gdb, which attaches to the current process and shows
a stack trace. The prompt is then shown again.

the program name (which will work correctly if gdk_init() or
gtk_init() has been called)
