	(mtrace): Register tr_memalignhook.
	(muntrace): Deregister tr_memalignhook.
	* malloc/malloc.c (__posix_memalign): If __memalign_hook != NULL,
	call it directly instead of memalign_internal.

	* posix/regexec.c (re_search_internal): Limit search to the
	beginning of the buffer if the initial states are empty for
