I compared the simple from the FE with -save-temps (FAILS) and without (OK)

the only difference between the two cases is that the temporary numbers are
different by two (the numbers are +2 for the case without save temps).  That is
the same as the difference shown in the report - but not sure how to analyse
that further right now ...
