gr_satellites receives SIGSEGV when run

[Chris Gorman]

Hello All,

I'm trying to run gr_satellites under gnuradio-3.8.2.0 and am getting
a segfault.  I was wondering if anyone else has experienced this or
has any suggestions.

I've run it through gdb and here's what I get...

(gdb) run /opt/gnuradio/bin/gr_satellites 1KUNS-PF --sa 48e3 --wavfile
satellite-recordings/1kuns_pf.wav
Starting program: /usr/bin/python /opt/gnuradio/bin/gr_satellites

I have tried to update python and get the same results with 3.9.1 as I
did with 3.8.5.  I did consider updating volk, but it seems that 2.0
is paired with gnuradio-3.8.2.0.  Is there a way to update volk in the
stable branch?

Thanks in advance,

Chris
