test case
Google ref: b/15734838
Test case compiles fine with Clang and current gcc-4_8-branch (@r211826).
Broken on trunk (and gcc-4_9) since not later than r195189.
Using current trunk @r211826:
gcc-svn-install/bin/g++ -c -std=c++11 t.cc
t.cc: In instantiation of 'std::function<_Res(_ArgTypes
...)>::function(_Functor) [with _Functor = C<>::<lambda()><H, int>;
