The following invalid testcase triggers an ICE on mainline:

=========================================
template<void> struct A;

template<typename> struct B;

template<void N> struct B<A<N> > {};
=========================================

bug.cc:1: error: 'void' is not a valid type for a template constant parameter
bug.cc:5: error: 'void' is not a valid type for a template constant parameter
bug.cc:5: error: 'N' was not declared in this scope
bug.cc:5: error: template parameters not used in partial specialization:
bug.cc:5: internal compiler error: tree check: expected tree_list, have
error_mark in process_partial_specialization, at cp/pt.c:2693
Please submit a full bug report, [etc.]

This is probably fallout from PR 27668.
