* src/heapallocate.c: Do not allow the size to overflow when
adjusting it. A test allocated a stack of -1 (~0). This
actually resulted in a stack being allocated but with a
size of 0xb. The allocator did not test the size to see if
it rolled through 0 and so allowed the allocation to happen, the
thread to get created. The task crashed as you would expect.
