Are you really meaning to use GCC 4.2 (that is ancient)?

I can reproduce your problem, but only with gcc-4.2.
Clang works just fine.
Here are the compiler versions I am using:

drago:llvm meadori$ gcc-4.2 --version
couldn't understand kern.osversion `14.3.0'
i686-apple-darwin11-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)
Copyright (C) 2007 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

drago:llvm meadori$ gcc --version
Configured with:
--prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.3.0
Thread model: posix

Hope that helps,
