Update.
2003-11-25 Ulrich Drepper <drepper@redhat.com>
* posix/runptests.c (main): Make errors fatal.
* posix/PTESTS: One test in GA135 and GA136 check functionality
which seems not guaranteed.
2003-11-25 Jakub Jelinek <jakub@redhat.com>
* posix/regexec.c (re_search_internal): If prune_impossible_nodes
returned REG_NOMATCH, set match_last to -1. Don't initialize
pmatch[0] needlessly. Fix comment.
(prune_impossible_nodes): Don't segfault on NULL state_log entry.
(set_regs): Fix comment.
* posix/regcomp.c (parse_bracket_exp): Only set has_plural_match
if adding both SIMPLE_BRACKET and COMPLEX_BRACKET.
(build_charclass_op): Set has_plural_match if adding both
SIMPLE_BRACKET and COMPLEX_BRACKET.
* posix/bug-regex11.c (tests): Fix register values for one commented
out test. Add new tests.
* posix/regex_internal.c (re_string_allocate): Make sure init_len
is at least dfa->mb_cur_max.
(re_string_reconstruct): If is_utf8, don't fall back into
re_string_skip_chars just because idx points into a middle of
valid UTF-8 character. Instead, set the wcs bytes which correspond
to the partial character bytes to WEOF.
* posix/regexec.c (re_search_internal): Allocate input.bufs_len + 1
instead of dfa->nodes_len + 1 state_log entries initially.
* posix/bug-regex20.c (main): Uncomment backwards case insensitive
tests.
