Ulrich Drepper 447777715a Update.
2003-12-29  Jakub Jelinek  <jakub@redhat.com>

	* posix/regexec.c (re_copy_regs): Revert comment change.
	Avoid memory leak if realloc fails.
	(proceed_next_node): Return -2 if re_node_set_insert fails.
	Return -2 if push_fail_stack fails.
	(push_fail_stack): Change fs->alloc only after successful
	realloc.
	(pop_fail_stack): Formatting.
	(set_regs): If proceed_next_node returns -2, free eps_via_nodes
	and fs.
	(check_arrival_add_next_nodes): Merge identical statements
	from if branches.

	* signal/Makefile (tests): Add tst-raise.
	* signal/tst-raise.c: New test.
