Description
This line of code gives an exception:
wregex exp(L"fo(o|b)ar \\1", regbase::extended);
It seems to be the \1 part that cause the problem.

Right - POSIX extended regular expressions don't support backreferences - use Perl compatible re's if you want that feature.

Sorry I now realize that
regbase::extendedincludesregbase::no_bk_refs.
