The following invalid code snippet triggers a ICE on mainline and 4.1 branch:
===================================================
template<void> struct A;
template<template<int> class> struct B {};
B<A> b;
===================================================
bug.cc:1: error: 'void' is not a valid type for a template constant parameter
bug.cc:5: internal compiler error: tree check: expected tree_list, have
error_mark in coerce_template_template_parms, at cp/pt.c:3792
Please submit a full bug report, [etc.]
This is fallout from PR 27668.
