    The 7 pad bytes at p-7 are not all FORBIDDENBYTE (0xfd):

    Because memory is corrupted at the start, the count of bytes requested
       may be bogus, and checking the trailing pad bytes may segfault.
    The 8 pad bytes at tail=0xddde5677967c12fd are fish: Job 1, './python c.py' terminated by signal SIGSEGV (Address boundary error)
