C++ std::regex implementation in different compilers

Question

Consider the following code.

std::regex re ("(qwe|asd|zxc)+");
std::cout << std::regex_match ("zxcqweasd", re) << std::endl;

When I use the cl compiler program prints 1 and 0 if I use the g++ compiler.

Which std::regex implementation is wrong?

I'm using g++ compiler version 4.7.2-5 and cl compiler version 17.00.60610.1.

g++ regex is not implemented fully. http://stackoverflow.com/questions/12530406/is-gcc4-7-buggy-about-regular-expressions — clcto, Oct 28 '13 at 20:15
@clcto - "not implemented fully" - I suppose, in marketing talk. "Implemented only as useless stubs" is more accurate. — Pete Becker, Oct 30 '13 at 15:57

gcc 4.7 has not complete standard library support for c++11. Regex is the main part missing.

cl compiler is correct.
