The OP's issue is that, in the simple example, it is known that there is enough free contiguous memory to allocate the HugeStruct because of that free() operation in step two should release the one chunk of allocated memory. Yet because of...

I ran Chris's code. I get the same output. This is weird. Why isn't free() moving the end-of-heap memory pointer back where it should be? Chip
