Neither should happen. 1. Is it consistently reproducible for you on the same file(s)? 2. Does MAKEOPTS=-j1 work as a workaround?

MAKEOPTS="-j1" worked. Sorry for the false alarm. This particular combination of flags with 10.1.0 seems sensitive on my machine.
(In reply to Andy Pettinger from comment #6) > MAKEOPTS="-j1" worked. Woohoo! I was afraid of that. > Sorry for the false alarm.

It's just hard to reproduce and debug on my machine :)
Please make a new bug if this still exists in current gcc.
