The following invalid testcase triggers an ICE on mainline:
=========================================
template<int,void> struct A {};
template<int N> struct A<N,0> {};
=========================================
bug.cc:1: error: 'void' is not a valid type for a template constant parameter
bug.cc:3: error: partial specialization 'A<N, <expression error> >' does not
specialize any template arguments
bug.cc:3: internal compiler error: tree check: expected tree_list, have
error_mark in process_partial_specialization, at cp/pt.c:2737
Please submit a full bug report, [etc.]
The ICE happens in the same function as PR 28737, but in a different position.
This is probably fallout from PR 27668.
