[Bug tree-optimization/27858] New: ICE in spill_failure, at reload1.c:1911while bootstrapping 4.2 on alpha

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I get the following ICE when bootstrapping gcc 4.2 20060530 on alpha.  20060508
worked fine.  I'm running delta right now and will send a test case when it's
done.
