The following invalid code snippet triggers an ICE since GCC 3.4.0:
=================================================
struct A
{
template<template<int> class B> struct B<0>;
};
=================================================
bug.cc:3: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have bound_template_template_parm in
finish_member_template_decl, at cp/pt.c:228
Please submit a full bug report, [etc.]
Before, the code was wrongly accepted. (The fact that in-class specializations
are allowed at all is tracked in PR 28300.)
