Comment:

 Fixed by svn r565. The fix will appear in Q2C25.

 The root cause of the problem was an ordering problem between the
 allocation
 of the cpu-state array and the setting of a value within that array.  That
 problem has been latent forever, but just now showed up due to an
 improvement
 in the exception handling capabilities of the OFW compilation environment.
 The reason it didn't bite us before was because the base address pointer
 for
 the cpu-state array happened to be 0 before, and too-early access of an
 array
 member thus happened to hit extant memory.
