mmmalloc

mmmalloc is a misoptimised memory allocator: my own malloc, free, calloc and realloc. It is the new version of hallocator, my previous allocator: memory now grows dynamically and calloc is implemented.

void *malloc(size_t size);
void free(void *_Nullable ptr);
void *calloc(size_t nmemb, size_t size);
void *realloc(void *_Nullable ptr, size_t size);

They follow the usual C11 and POSIX semantics, with one difference: size must be greater than 0 (the non-GNU approach). On error they return NULL and set errno to ENOMEM; nothing makes the program exit.

If you notice strange behaviour you think comes from the allocator, open an issue.
