GDB doesn't call abort (well ok, there's one call :-) Instead for cases 
like this GDB should call internal_error.

If this happens, GDB's shot itself in the foot so might as well call 
internal_error here as well.

Jim, since you're handling this, can I assume that you'll clean up any 
nuences that the ARI identifies (as I did for the last round of s390 
patches).  It will save Ulrich the need of respining what are basicly 
correct patches.
