The following invalid code snippet triggers an ICE on mainline:
===============================
template<typename T> struct A
{
__decltype (T* foo());
};
===============================
bug.cc:3: error: expected primary-expression before '*' token
bug.cc:3: error: there are no arguments to 'foo' that depend on a template
parameter, so a declaration of 'foo' must be available
bug.cc:3: error: (if you use '-fpermissive', G++ will accept your code, but
allowing the use of an undeclared name is deprecated)
bug.cc:3: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
The problem appeared between 2007-07-16 and 2007-08-15, presumably with
the introduction of decltype:

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

While PR33839 and PR33837 got fixed, this ICE still persists.
