<div>
<pre>I find bug in libc++ in regex. This is my code sample:
#include <iostream>
#include <regex>
#include <string>
int main() {
std::string HW("HelloWorld");
std::regex RE("[^\\W]");
if (std::regex_search(HW, RE))
std::cout << "regexp is OK";
else
std::cout << "regexp is broken";
std::cout << std::endl;
return 0;
}
This is my command for compilation:
clang++ -std=c++11 -stdlib=libc++ main.cpp
And I get:
regexp is broken
But, if I use libstdc++ :
clang++ -std=c++11 -stdlib=libstdc++ main.cpp
It's ok:
regexp is OK
I get bug only for regexp [^\\W] and for combinations with it.
I use libc++dev form ubuntu version: 3.9.1-2</pre>
