Confirmed but minor as this is an error recovery problem.

>From Phil's regression hunter: Search converges between 2002-12-27-trunk (#177) and 2002-12
-28-trunk (#178). aka the new parser caused this one.

Here's a similar testcase that crashes since gcc 2.95.x:

==========================================
struct A
{
    int foo() { return sizeof(bar); }
    int bar();
};
==========================================

With checking enabled I don't even get a decent error message before the
tree check failure.
