Urgh. +relay seems to indicate that CPUID was used just before the exception
happened.  Earlier I verified that the code is testing for SSE and SSE2 flags
(although disabling these checks didn't avoid the FPE).  This makes sense, but
contradicts my former supposition.  I'm not sure about anything now (maybe this
FPE is just the wrong thing to look at?) :-(
