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.
