[Bug objc++/28434] New: ICE with invalid protocol

[reichelt at gcc dot gnu dot org]

The following invalid testcase triggers an ICE since GCC 4.1.0
(when objective-c++ was introduced):

====================
Class<> c;
====================

bug.mm:1: error: expected identifier before '>' token
bug.mm:1: internal compiler error: tree check: expected identifier_node, have
error_mark in lookup_and_install_protocols, at objc/objc-act.c:1438
Please submit a full bug report, [etc.]

Posting a patch soon.
