[Bug c++/32560] New: [4.3 regression] ICE on invalid declaration in template

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE on mainline:

=============================================
namespace N {}

template<typename> struct A
{
  int A<typename N::X>;
};
=============================================

bug.cc:5: error: 'X' in namespace 'N' does not name a type
bug.cc:5: error: template argument 1 is invalid
bug.cc:5: error: expected `::' before ';' token
bug.cc:5: error: expected `*' before ';' token
bug.cc:5: error: expected unqualified-id before ';' token
bug.cc:5: internal compiler error: in cp_parser_make_indirect_declarator, at
cp/parser.c:2714
Please submit a full bug report, [etc.]

The regression was introduced between 2007-05-26 and 2007-06-07,
probably by the patch
