Thanks. After trying and failing to convince it to fail in cross environment,
it finally dawned on me that the failure was during stage 2, so presumably
this is a miscompile of cc1plus. Sorry for the runaround.
I'll try to reproduce the failure on gcc62, but I'm guessing it will take
a while to reach the failure point.
