             Bug #: 53631
           Summary: [C++11] <regex> is unimplemented
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: redi@gcc.gnu.org


This is a placeholder bug for the missing <regex> functionality.

It's documented as missing in
http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2011

The whole of Clause 28 is partially supported or not supported at all.

Until someone works on it there is really no point reporting bugs against
individual features.
