            Bug ID: 57953
           Summary: no C++11 compliant std::ios_base::failure found
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: unixway.drive+gcc at gmail dot com

§27.5.3 states that "ios_base defines <...> a class failure derived from
system_error". The only std::ios_base::failure I see in a libstdc++ is a
pre-C++11 ones.

$ g++ -v

And http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2011
states this isn't implemented yet.
