[Bug c++/28637] New: [4.1/4.2 regression] ICE on invalid template parameter

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers a segfault on mainline
and 4.1 branch:

===============================
template<void> struct A {};
A<0> a;
===============================

bug.cc:1: error: 'void' is not a valid type for a template constant parameter
bug.cc:2: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

This is fallout from PR 27668.
