             Bug #: 56193

           Summary: ios_base should replace operator void* with explicit

                    operator bool in C++11 onwards.

    Classification: Unclassified

           Product: gcc

           Version: unknown

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: libstdc++

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: 3dw...@verizon.net





As pointed out on SO, g++ still compiles:



std::cout << std::cout



In C++11 the stream testing operator was changed from:

  operator void*() const;

to:

  explicit operator bool() const;



A quick patch is being tested now.

The target is 4.9 even though it is simple.
