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>, >':
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../include/c++/4.8/bits/shared_ptr_base.h:992:
