Are you 100% sure? If GCC have bugs writing out-of bounds the amount of memory 
can change the scheme and generate different corruptions. I'm not sure if that 
can trigger the checks in GCC, but I think that isn't in malloc, and I know 
isn't related with CWSDPMI because I saw it under W95.

But can the use of TMPDIR change when the amount of memory changes?
