The following invalid testcase triggers an ICE on mainline:
=========================================
template<void> struct A
{
template<typename> friend struct B;
};
template<typename> struct B {};
B<int> b;
=========================================
bug.cc:1: error: 'void' is not a valid type for a template constant parameter
bug.cc:3: internal compiler error: tree check: expected var_decl or
function_decl or type_decl or template_decl, have error_mark in
most_general_template, at cp/pt.c:11253
Please submit a full bug report, [etc.]
This is probably fallout from PR 27668.
