You could try changing all optimization flags
to -L0 in the Makefile, and see if this gives
no NaN's. If so, you could then try turning
optimization back on for each file in turn
(or more efficiently for half at a time for
binary search) until you isolate the problem.

It would be interesting to keep timing results
for such experiments to see what effect the
optimization has.
