--- Comment #17 from Segher Boessenkool <segher at gcc dot gnu.org> --- Why does this happen so extremely often for s390x customers? It should from first principles happen way more often for e.g. powerpc, but we never see such big problems, let alone "all of the time"! So what is really happening? And, when did this start, anyway, because apparently at some point in time all was fine?
