[Bug c++/28111] New: ICE with invalid friend in template class

[reichelt at gcc dot gnu dot org]

The following invalid code snippet causes an ICE since at least GCC 2.95.3:

=================================
template<typename> void foo();

template<typename T> struct A
{
    friend void foo<>(typename T::X);
};

A<int> a;
=================================

bug.cc: In instantiation of 'A<int>':
bug.cc:8:   instantiated from here
bug.cc:5: error: 'int' is not a class, struct, or union type
bug.cc:5: internal compiler error: tree check: expected function_type or
method_type, have error_mark in determine_specialization, at cp/pt.c:1396
Please submit a full bug report, [etc.]

Testing a patch.
