           Summary: ICE on ill-formed alias template declarations
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0

The following tests from clang's alias templates testsuite all cause g++ svn to
ICE:

template<typename Z> using ::T = void(int n);
template<typename Z> using operator int = void(int n);
template<typename Z> using typename U = void;
template<typename Z> using typename ::V = void(int n);
template<typename Z> using typename ::operator bool = void(int n);
