                    std::ostream-in-std::basic_ostringstream<char,
                    std::char_traits<char>, std::allocator<char> >'
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED

I'm trying to build GCC 4.8 for x86_64-w64-mingw32. I have a cross-compiler but
I cannot build my C++ code with it.

The error is exactly the same as the one detailed here:
http://gcc.gnu.org/ml/gcc-patches/2012-05/msg01142.html

I seem to be unable to detect when exactly this problem shows up, but I run
into it when building PPL-0.12.1 with the Linux->Windows cross-compiler:

/bin/bash ../../libtool  --tag=CXX   --mode=link x86_64-w64-mingw32-g++  -g -O2

This effectively makes g++ useless. I seem to remember only non-debug builds
are affected.
