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.
