  Hmm. Look like it's the returning of the high limb via the separate *qp

I traced it to a nn=0 call to the underlying pi1 call.  Dunno if that's
problematic.

Or it is a compiler problem, considering that it seems to happen on just
s390.  Or an assembly bug.

(I will get to this at some point, but probably the next week.)
