[Bug c++/33839] New: [4.3 regresssion] ICE with decltype


The following code snippet triggers an ICE on mainline
(I'm not sure whether this is valid or not):

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

void foo()
{
  __decltype A<0>;
}
===============================

bug5.cc: In function 'void foo()':
bug5.cc:9: internal compiler error: in cp_parser_lookup_name, at
cp/parser.c:16084
Please submit a full bug report, [etc.]

The problem appeared between 2007-07-16 and 2007-08-15, presumably with
the introduction of decltype:

2007-07-27  Douglas Gregor  <doug.gregor@gmail.com>

        * typeck.c (structural_comptypes): Compare DECLTYPE_TYPE nodes.
        * cp-tree.def (DECLTYPE_TYPE): New.
        * error.c (dump_type): Dump DECLTYPE_TYPE nodes.
        ...
