I performed a local experiment, first building sources from r318784
on a system where I did pre-commit test for ino64, updating the machine
to the result of it, then building sources of r318789 and again updating.

No SIGSEGV etc, so I think that the effects seen are due to build system.
rm -rf obj/* is the safest trick, I believe.
