Save that to a .cc file and try $ g++ -std=c++11 -c test.cc $ g++ -o test test.o using the same g++ version that you use for webkit.
I'm not the one who filed this bug, but I have the same compile failure. So I did the test you mentioned: [[ In case of "x86_64-pc-linux-gnu-4.7.3" ]] $ gcc --version gcc (Gentoo 4.7.3-r1 p1.3, pie-0.5.5) 4.7.3 Copyright (C) 2012 Free Software Foundation, Inc.

As far as I remember this failure is avoided if you pass '-D_GLIBCXX_USE_SCHED_YIELD -D_GLIBCXX_USE_NANOSLEEP' among the C++ compiler flags when compiling with GCC 4.7. Can you try that out?
Hello, I've also ran into that issue... (In reply to comment #6) > As far as I remember this failure is avoided if you pass '-D_GLIBCXX_USE_SCHED_YIELD -D_GLIBCXX_USE_NANOSLEEP' among the C++ compiler flags when compiling with GCC 4.7. > > Can you try that out? Nope, that doesn't work for me... nor for the webkit, nor for the test example.
Just found: https://bugs.gentoo.org/show_bug.cgi?id=513386 It seems the issue is in the gcc ABI changes... And a bit specific gentoo ld.so.conf order.
Is this still an issue?
Well from a skim of the detailed Gentoo bug and the shorter GCC one, it seems this boils down to (quote from the GCC bug) "It is totally unsupported (and unlikely to work) to mix C++11 code built with GCC 4.x and 4.y, for any x!=y" -- which is apparently what's happened here -- so I'd say this is NOTABUG. From the Gentoo bug: "GCC upstream emphasized that they won't support the Gentoo approach to handling libstdc++ for C++11, namely the use of a 4.8 libstdc++ with code compiled by 4.7. So we need to address this at the distro level, one way or another, at least until upstream officially declares its ABI stable."
Thanks for the clarification Michael.
