* lib/regcomp.c (init_dfa): Tighten overflow checks to test
for IDX_MAX too, since IDX_MAX can be much less than SIZE_MAX.
(init_word_char): Work even if bitset words are not exactly 32 or
64 bits wide. Don't assume there are no padding bits.
* lib/regex.c [_LIBC]: Do not include <config.h>.
[!_LIBC]: Add pragmas to ignore -Wsuggest-attributes=pure
and -Wtype-limits.
* lib/regex.h (__USE_GNU): Renamed from __USE_GNU_REGEX, to avoid
needless disagreement with glibc. All uses changed. Define it to
1 only if _GNU_SOURCE, to match glibc.
(_REG_RM_NAME): Remove; no longer needed, since the names in
question are now all protected by __USE_GNU.
(_REG_RE_NAME): Remove; replaced by glibc's __REPB_PREFIX.
(REG_TRANSLATE_TYPE): Remove; replaced by glibc's __RE_TRANSLATE_TYPE.
* lib/regex_internal.h (MIN): New macro.

* lib/regex_internal.c (re_string_fetch_byte_case):
Fix up regcomp/regexec. 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;
}

* lib/regcomp.c (build_equiv_class):
Fix access after end of search string in regex matcher.
2011-10-12 Ulrich Drepper <drepper@redhat.com>
* lib/regcomp.c (parse_branch): One more regex memory leak fixed.
2011-10-11 Ulrich Drepper <drepper@redhat.com>
* lib/regcomp.c (parse_branch, parse_sub_exp):
More regex memory leak fixes and tests.
(parse_sub_exp, parse_bracket_exp):
Fix memory leak for some invalid regular expressions.
2011-05-28 Ulrich Drepper <drepper@gmail.com>
* lib/regex_internal.c, lib/regexec.c:
Fix unnecessary overallocation due to incomplete character. 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.
2011-05-20 Reuben Thomas <rrt@sc3d.org>
* lib/regex.h: Update documentation.
2010-05-05 Andreas Schwab <schwab@redhat.com>
* lib/regexec.c (find_collation_sequence_value):
Fix lookup of collation sequence value during regexp matching.
2007-11-26 Ulrich Drepper <drepper@redhat.com>
* lib/regex.h (REG_ENOSYS): Define REG_ENOSYS also for __USE_XOPEN2K.
2007-08-26 Ulrich Drepper <drepper@redhat.com>
* lib/regex_internal.h: Prevent some declarations and definitions
to be seen when used in tests.
2005-05-06 Ulrich Drepper <drepper@redhat.com>
* lib/regex_internal.h: Include bits/libc-lock.h or define dummy
__libc_lock_* macros if not _LIBC.
(struct re_dfa_t): Add lock.
