Nathan, this was caused by your patch
http://gcc.gnu.org/ml/gcc-cvs/2003-06/msg00871.html

Apparently we have a tcc_exceptional in the last switch
statement of cp_tree_equal so that we hit gcc_unreachable.

I don't know whether tcc_exceptional should be handled more
gracefully or whether it shouldn't appear there at all.
