You really shouldn't :)

Since the problem occurs randomly it has most probably something to do
with a pointer, that hasn't been nulled, after the memory is free()'d. Later,
when the program then attempts to access the memory location, that the
pointer is pointing to, the adress may be used by other applications, other
vars, or something else entirely.

The STATUS_ACCESS_VIOLATION exception occurs in the case mentioned above, as
well as if you try to access memory at NULL. A solution to your problem would be, if you
ran the mud through gdb. This would give you an idea of where in the source you have a problem.
Info on how to debug with gdb is in the FAQ at ceramic mouse:

Well, help for self-help :)
