Comment (by jpflori):
I think I got the smattest issue.
This must be a type length issue (and several warning about overflow in
xmod.h during compilation should have made me realize it earlier).
In smat_elim.cc, if I use the "works fine" code in xmm0 rather than the
David Harvey's one, the test passes.
I think the problem is with INV_BIGPRIME being defined as long, which is
32 bits here on Cygwin I guess and does not fit (1<<33)+140!) rather than
int64_t, whence the warnings during compilation.
I'm recompiling right now and will retest.
If that's indeed the problem, that should not be restricted to Cygwin but
anywhere where long is only 32 bits.
