12: free helps you manage the arena. It returns to the free memory
13: pool memory that had previously been allocated by malloc, calloc,
14: or realloc. free marks the block indicated by _p_t_r as unused, so
15: the malloc search can coalesce it with contiguous free blocks.
16: ptr must have been obtained from malloc, calloc, or realloc.

29: free prints a message and calls aabboorrtt if it discovers that the
30: arena has been corrupted. This most often occurs by storing data
31: beyond the bounds of an allocated block.
