[Bug c++/32113] New: [4.1/4.2/4.3 regression] ICE with invalid template parameter

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following invalid code snippet triggers an ICE since GCC 4.1.0:

=====================================================
template<int> struct A;

template<typename T> void foo (A<&T::template i>);

template void foo<A<0> > (A<0>);
=====================================================

bug.cc:3: error: '#'unbound_class_template' not supported by
dump_decl#<declaration error>' is not a template
bug.cc:5: internal compiler error: in lookup_member, at cp/search.c:1203
Please submit a full bug report, [etc.]

Btw, the hosed diagnostic in the first line of the error message is tracked
in PR 32112.
