No....that's one thing I've noticed about Fortran runtime errors...no line
numbers in the popup.  I was wondering if that option is turned off during
build.

I do see in filbig.f90 where ca was shrunk from NFFT1 to NFFT1/2+1.  But
don't see how it can get that index unless it's in the FFT itself.

Does the error message report a line number?
