This is most probably a subtle bug in your program that went unnoticed
in v2.01.  The new malloc doesn't keep slack space beyond the end of
the allocated buffer, so programs which overrun the allocated storage
run much higher risk of destroying the chain of pointers maintained by
malloc and free.

In general, I expect many similar bugs to be revealed by upgrading to
v2.02.

I would rather suggest to debug your program ;-).
