Update.

1998-08-28 09:22  Ulrich Drepper  <drepper@cygnus.com>

	* elf/rtld.c (process_envvars): Fix copy&paste error.

	* malloc/malloc.c (malloc_hook_ini): Don't overwrite realloc and
	memalign hook.
	(realloc_hook_ini): Don't overwrite memalign hook.
	(memalign_hook_ini): Don't overwrite malloc and memalign hooks.
	Reported by Philippe Troin <phil@fifi.org>.

	* malloc/mcheck.c (mprobe): Call checkhdr with adjusted pointer.
	Patch by Philippe Troin <phil@fifi.org>.

1998-08-26  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/generic/segfault.c (install_handler): Protect the
	non-POSIX signals with #ifdef.
	(catch_segfault): Add missing mode parameter for open.
	* debug/catchsegv.sh: Avoid termination message from shell.  Allow
	other termination signals.
