Hello Michael, you were right! It does not crash now with paxctl +m in 
/usr/pkg/bin/jt9 binary


netbsd-nuc# paxctl  /usr/pkg/bin/jt9
PaX flags:
  m: mprotect(2) restrictions, explicit disable
netbsd-nuc#

decoder does not crash now:

netbsd-nuc$ jt9 -8 170923_082000.wav
<DecodeFinished>   0   0        0

But unfortunately WSJTX does not show decodes when feeding the program 
with test audio files.

I will continue investigating.

Regards.
