Update.
2001-12-06  Ulrich Drepper  <drepper@redhat.com>

	* libio/vasprintf.c (_IO_vasprintf): Free buffer on failure.
	* assert/assert.c: Check result of __asprintf call and don't use
	string if it failed.
	* assert/assert-perr.c: Likewise.
	* inet/rcmd.c: Likewise.
	* locale/programs/localedef.c (main): Check result of
	construct_output_path and exit if it failed.
	(construct_output_path): Check result of asprintf and mkdir calls and
	fail if they failed.
	* posix/getopt.c: Check result of __asprintf calls and fail if
	they failed.
	Patch by Dmitry V. Levin <ldv@alt-linux.org>.
