The following valid code snippet triggers an ICE on the 4.8 branch and trunk:
==========================================
template<int&> struct A
{
template<typename> struct B;
template<typename T> struct B<T*> {};
};
==========================================
bug.cc:5:35: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have template_decl in lookup_template_class_1,

Please submit a full bug report, [etc.]
The example compiles fine with GCC 4.8.0 - 4.8.2.
The regression might be fallout from the fix for PR58606.
Jason, would you mind having a look?
