Rich Felker	b761bd19aa	fix rare but nasty under-allocation bug in malloc with large requests the bug appeared only with requests roughly 2sizeof(size_t) to 4sizeof(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).	15 years ago
Rich Felker	bf8785825a	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.	15 years ago
Rich Felker	0958200166	very cheap double-free checks in malloc	15 years ago
Rich Felker	26031da0f8	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.	15 years ago
