If they are related (which I doubt), removing the call to cleanup_cfg
in cfgexpand.c should fix them. That's the only real change in
this patch - previously the cleanup_cfg call was conditional on a
present EH region tree (thus, all of these issues are latent and
just require a slightly different testcase)
