Bug#980472: cubicsdr: CubicSDR crashes after lauch! (same effect on 2 clean bullseye OS)

[LH <louis.hb@bluewin.ch>]

    Hi there
    
    Questions from hamlib:
    
    1)
    Does startup work if you first disconnect one of
      the receivers?
    No, it does not start! It crashes as described. (No difference
    whether the SDR-Reciever is connected or not; CubicSDR crashes.)
2)
Do you have anything configured for hamlib radio control?
No, I have not configured anything. Just installed CubicSDR from Synaptic.
(CubicSDR was the first additional Software after installing Bullseye - incl. apt update/ apt upgrade of course.)

3)
Hmm. Can exit() lead to segfaults in threaded programs?
I cannot answer that.
    To Christoph:
    Your 'backtrace' Links: I will give it one more try. I will let you
    know.
    
    Best
    Louis HB
