 Thanks for the feedback. I only tried with gcc not with g++.
 I now can reproduce this, cc1plus segfaults even without ANY
 input file if -quiet and -fstats is passed. This one line patch
 (compiled but not bootstrap tested) fixes the ICE for me, not sure
 if this is the appropriate fix though. Someone please look at this
 and check it in if appropriate.
