Here's an excerpt from the free(3) man page: free() frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behaviour occurs. If ptr is NULL, no operation is performed. It doesn't says: "If ptr is NULL, the program may crash".
