Comment (by kcrisman):
> > > IIRC (and I'm quite sure I am) I got segfault as well during the
tuning itself on Cygwin (64bits Windows 7), mostly when issuing make with
MAKE="make -j4" so the system must have been busy as well, but IIRC (less
sure) it also happened when building zn_poly alone.

Correct; with one other spkg being built it was too much. Segfault during
tuning in KS/FFT mul, repeatable. No problems during short self-test,
though of course I couldn't try that without using just one thread in any
case.
> Building itself (before and/or after tuning) can also fail?
I guess not.
