Hmm. I wasn't able to reproduce this using my instrument on a 64 bit Linux
using either V1.0.3 or V1.1.0. It's possible that it is peculiar to
your particular instrument, in that it is sensitive to the calibration
information in it.

In my situation no more than 4 of the 64 filter slots get used in
high res mode. Try un-commenting the diagnostic

        printf("~1 fshmax = %f\n",fshmax);

at about line 6775 (in V1.1.0)

and also add/uncomment the line

        printf("~1 filter %d, cwl %f, rwl %f, ix %d, we %f, nocoefs 

at about line 6880 and see what this reveals (I've added nocoefs to it here).
