Extended Description

Gcc compiles the following fragment without errors.

clang++ crashes with the following assertion failure at SemaTemplateInstantiateDecl.cpp:2219.

The fragment was reduced from a boost header file.

==================== template
struct class_has_move_assign {
class type { typedef T E;
template // subsitute T for E and bug goes away struct sfinae { }; 

  template <class U>  
  typename sfinae<&U::operator=>::type test(int);

}; };
