'size_t' is defined as 'unsigned' in, e.g., stdlib.h, but is it impossible to allocate more than 32,764 bytes at once?

I found a JGE instruction in malloc's code, but why do you a signed comparison?

Which function did you find that in? _nmalloc?

Probably. ;-) I didn't debug the RTL, but the generated test executable. I use the small memory model (option '-ms') and the instruction was 'call near ptr _malloc'. Hope, this helps!

Um, still waiting... :-(
