Currently we fail to notice integer overflow when parsing a back-reference expression, or when converting the parsed result from long to int. This changes the result to be int, so no conversion is needed, and uses the overflow-checking built-ins to detect an out-of-range back-reference. libstdc++-v3/ChangeLog: PR libstdc++/106607 * include/bits/regex_compiler.tcc (_Compiler::_M_cur_int_value): Use built-ins to check for integer overflow in back-reference number. * testsuite/28_regex/basic_regex/106607.cc: New test. |
