From 33e63e7993d50ca4a8409aefaccf247301c0e8f2 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 4 Jun 2006 04:59:36 +0000 Subject: [PATCH] * posix/regex_internal.c (re_string_skip_chars): If no character has been converted at all, set *last_wc to WEOF. If mbrtowc failed, set wc to the byte which couldn't be converted. (re_string_reconstruct): Don't clear valid_raw_len before calling re_string_skip_chars. If wc is WEOF after re_string_skip_chars, set tip_context using re_string_context_at. * posix/Makefile: Add rules to build and run bug-regex25 test. * posix/bug-regex25.c: New test. --- ChangeLog | 11 ++++++++++ posix/Makefile | 3 ++- posix/bug-regex25.c | 57 ++++++++++++++++++++++++++++++++++++++++++++++++++ posix/regex_internal.c | 26 +++++++++++++++-------- 4 files changed, 87 insertions(+), 10 deletions(-) create mode 100644 posix/bug-regex25.c diff --git a/ChangeLog b/ChangeLog index c299adc3e3..6999e7d1e7 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,14 @@ +2006-06-02 Jakub Jelinek + + * posix/regex_internal.c (re_string_skip_chars): If no character has + been converted at all, set *last_wc to WEOF.
