I havent analyzed in detail, but I think that as consequence of not
finding a reasonable white patch, the conversion from spectral to XYZ

is not prepared to deal with NaN numbers.
cgats.c/real_format() returns a nonsense format ("%6.-2147483644f"),
and the Mac printf then goes into an infinite loop.
I think that the I8 illuminant having zero output at certain
wavelengths is causing the NaN's.
