Code file that clang has trouble compiling
Please see attached file clang_bug.cc. When I compile it with clang, I get a
linker error as given below. The file compiles fine with g++ 4.8.1.
clang++ -std=c++0x -g clang_bug.cc
/tmp/clang_bug-aZhS4N.o: In function
`__shared_ptr<std::allocator<SubClass::AnotherClass>, >':
