Without being able to determine the exact line in your program that
it died..you didnt list it, I would say that you are trying to
sprintf a null pointer into a buffer. This is proably the cause of
the _memcpy problem. Put a check in before the sprintf to make sure
that the variable is not null before trying to copy it to the buffer.
