Current CVS of teh tree-ssa branch does not bootstrap for me on
i686-linux-gnu, xgcc is miscompiled:

I get the same segv compiling crtstuff.c with the stage2 compiler just
built by stage1 and that is with and without rtl checking enabled.

Whoops not quite correct bootstrap succeeds without rtl checking and fails
with rtl checking due to the segv reported by Andreas.

I did some more digging and it would appear that it's insn-recog.c that's
being miscompiled by stage1/cc1. I haven't pinpointed the routine(s) that
are being miscompiled but I suspect recog_20 is one of them.
