| * | fix rare but nasty under-allocation bug in malloc with large requests•••the bug appeared only with requests roughly 2*sizeof(size_t) to
4*sizeof(size_t) bytes smaller than a multiple of the page size, and
only for requests large enough to be serviced by mmap instead of the
normal heap. it was only ever observed on 64-bit machines but
presumably could also affect 32-bit (albeit with a smaller window of
opportunity).

| * | avoid over-allocation of brk on first malloc•••if init_malloc returns positive (successful first init), malloc will
retry getting a chunk from the free bins rather than expanding the
heap again. also pass init_malloc a hint for the size of the initial
allocation.

| * | very cheap double-free checks in malloc | Rich Felker | 2011-03-23 | 1 | -0/+4 |
| * | make malloc(0) return unique pointers rather than NULL•••this change is made with some reluctance, but i think it's for the
best. correct programs must handle either behavior, so there is little
advantage to having malloc(0) return NULL. and i managed to actually
make the malloc code slightly smaller with this change.
