please use that one to verify your fix.

The fftw-wisdom binary is not expected to produce deterministic results, at least not in measure/patient/exhaustive (and there's little interest in having 'estimate' plans in the wisdom files). It only generates 'plans' for the specified transformations to enable deterministic reuse from those generated 'plans' afterward. It doesn't do more than the combination of 'fftw_plan()' and 'fftw_export_wisdom()'.
from fftw3.
Yes, it's not deterministic, because plan generation depends on runtime timing measurements. (fftw-wisdom
defaults to using FFTW_PATIENT
mode.) See the FFTW FAQ.

Thanks for that pointer to the FAQ. I can confirm that using fftwf-wisdom -e
makes output deterministic.
