* 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.
