linux and regex?

[Dy7SLyTq]

so im compiling with g++ 4.8.1 using the -std=c++11 flag, and i may have found a bug. using this code:
[code line=35]
try
{
while(regex_search(SubCounter, Match, regex("\"[^\"]*\"")))
{Log::Log(__LINE__, __FILE__);
int Line = 0;
TokenList.push_back(Token("STRING", SubCounter.substr(Match.position(0), Match.length(0)), ++Line, Match.position(0)));
SubCounter = SubCounter.substr(Match.length(0), SubCounter.size());
}
}

catch(exception &Error)
{
cout<< Error.what() << endl;
}
[/code]
i have verified that it is regex_match because as you can see on line 38 that it calls a function Log. that spits out a message that shows you it hit that line. it never gets called and instead goes to the exception about five times and says regex_error. my question is am i doing something wrong or is it a bug in regex?

AFAIK std::regex is broken in gcc < 4.9. Try boost::regex

damn :L i was hoping to avoid that... oh well. if i do sudo apt-get libboost-dev will that download the whole library with everything compiled that needs to be?

std::regex is broken in mainline GCC SVN
http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2011
(and it wont be fixed any time soon).

They added it just recently, per http://gcc.gnu.org/

C++11 <regex> support [2013-10-03]
Regular expression support in libstdc++-v3 is now available.

...now to wait another five years for the C++11 Unicode stuff (<regex> was a TR1 component, it was supposed to have been around since 07)

Thanks Cubbi.
