That bug has should have been fixed:

fft: replace fftwf_malloc with volk_malloc
fftwf might not be compiled with AVX, which results in improper
alignment when fftwf_malloc'd buffers are used in VOLK kernels. To fix
this, just replace all fftw_malloc/fftwf_free calls with
volk_malloc/volk_free calls with whatever alignment VOLK claims is
needed.
You should update your GNU Radio and (the included) Volk. If your
`gnuradio-config-info --version` reports v3.7.9.2 or v3.7.9.2-18 (or
>18), your GNU Radio should already contain that bugfix. If the version
is below v3.7.9.2-18, something went wrong during updating your GNU Radio.
Best regards,
Marcus
