I have the following regular expression object that I create:
(Full, working sample here)
When this regex object is constructed,
std::regex_error is thrown with code set to 2, which happens to be
std::regex_constants::error_escape. I did some process of elimination and when I remove the
\d, it works just fine.
I tested this on VS 2013 and it does not throw an exception. I tested this on Coliru and it seems to completely crash. If I use clang++ it works.
Why isn't this regex working on GCC? Am I doing something wrong?
