| | | | | | | | * posix/regex_internal.c (re_string_skip_chars): Fix miscomputation of remain_len that may cause incomplete multi-byte character and false match. * posix/bug-regex33.c: New file. * posix/Makefile (tests): Add bug-regex33.

* Fix up regcomp/regexecJakub Jelinek2011-12-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | The problem is that parse_bracket_symbol is miscompiled, and it turns out it is because of an incorrect attribute on re_string_fetch_byte_case. Unlike re_string_peek_byte_case, this one is really not pure, it modifies memory (increments pstr->cur_idx), and with the pure attribute GCC assumed it doesn't and it cached the presumed value of regexp->cur_idx in a variable across the for (;; ++i) { if (i >= BRACKET_NAME_BUF_SIZE) return REG_EBRACK; if (token->type == OP_OPEN_CHAR_CLASS) ch = re_string_fetch_byte_case (regexp); else ch = re_string_fetch_byte (regexp); if (re_string_eoi(regexp)) return REG_EBRACK; if (ch == delim && re_string_peek_byte (regexp, 0) == ']') break; elem->opr.name[i] = ch; }

* Fix unnecessary overallocation due to incomplete characterUlrich Drepper2011-05-281-10/+14
| | | | | | When incomplete characters are found at the end of a string the code ran amok and allocated lots of memory. Stricter limits are now in place.
