The following testcases cause an ICE on mainline:

====================
struct A
====================

====================
struct A {}
====================

The error message is

nase.cc:1: internal compiler error: in cp_lexer_consume_token, at
cp/parser.c:547
Please submit a full bug report, [etc.]

The regression was introduced yesterday or today.
I strongly suspect Nathan's patch
http://gcc.gnu.org/ml/gcc-cvs/2004-10/msg01185.html

Nathan, could you please have a look?
