-
- This symbol has been exported (as an internal GLIBC_PRIVATE symbol) from libc.so.6 starting with glibc 2.34. glibc uses it internally for its libthread_db implementation to enable thread debugging on GDB, so it is unlikely to go away for now.

+
+ libstdc++: Fix handling of invalid ranges in std::regex [PR102447]
+
+ std::regex currently allows invalid bracket ranges such as [\w-a] which
+ are only allowed by ECMAScript when in web browser compatibility mode.
+ It should be an error, because the start of the range is a character
+ class, not a single character. The current implementation of
+ _Compiler::_M_expression_term does not provide a way to reject this,
+ because we only remember a previous character, not whether we just
+ processed a character class (or collating symbol etc.)
+
+ This patch replaces the pair used to emulate
+ optional with a custom class closer to pair. That
+ allows us to track three states, so that we can tell when we've just
+ seen a character class.
+
+ With this additional state the code in _M_expression_term for processing
+ the _S_token_bracket_dash can be improved to correctly reject the [\w-a]
+ case, without regressing for valid cases such as [\w-] and [----].
+
+ libstdc++-v3/ChangeLog:
+
+ PR libstdc++/102447
+ * include/bits/regex_compiler.h (_Compiler::_BracketState): New
+ class.
+ (_Compiler::_BrackeyMatcher): New alias template.
+ (_Compiler::_M_expression_term): Change pair
+ parameter to _BracketState. Process first character for
+ ECMAScript syntax as well as POSIX.
+ * include/bits/regex_compiler.tcc
+ (_Compiler::_M_insert_bracket_matcher): Pass _BracketState.
+ (_Compiler::_M_expression_term): Use _BracketState to store
+ state between calls. Improve handling of dashes in ranges.
+ * testsuite/28_regex/algorithms/regex_match/cstring_bracket_01.cc:
+ Add more tests for ranges containing dashes. Check invalid
+ ranges with character class at the beginning.
+
+ (cherry picked from commit 7ce3c230edf6e498e125c805a6dd313bf87dc439)
