[Boost-users] exceptions from regexp library usage

Hi, I get the following exception while using a boost regexp matching libraries (with Windows Visual Studio, 7.1 environment). Setup: static RegexClass::RegularExpression re_exp; bool CMyclass::parseExpression(string expression) { LoggerPtr logger = Logger::getRootLogger(); ostringstream oss; RegexClass::RegularExpression *re = &re_exp; re->Expression = expression; RegexClass::RegularExpression::ExpressionErrorCode eec = re->ParseExpression(); if (eec == RegexClass::RegularExpression::REG_NOERROR) { oss << "Parse successful: " << expression; logger->info(oss.str()); return true; } ... } Matching call: bool CMyClass::matchSpec(RegexClass::RegularExpression *pRe, const char *stringToMatch) { pRe->SetStringToMatch(stringToMatch); if (pRe->Match()) { return true; } return false; } Exception while using expression matcher on Windows Server 2003 Platforms: Exception Stack Trace 0x0343c900 0x00457374 boost::re_detail::reg_grep2
