Satellite tracker crashes #1260

I am having Satellite tracker problems on SDRangel running on Raspberry Pi OS Bullseye 64 bit or DietPi Bullseye 64 bit. Same on both OS distributions.

Starting with version 6.19,
I added presets for the satellites that I have in Satellite tracker and configured SDRangel Control.
SDRangel will freeze when SDRangel Control starts a satellite path procedure while another Channel demod is running.
It freezes less often when there is nothing running between satellite passes.

The latest version that I tried with Satellite tracking working well was version 6.18.1.

Starting with version 6.19, in addition to the Satellite tracker crashes, the DSD demod constellation will freeze after running for a few minutes, sometimes longer.

I tried SDRangel version 7.2.1-8-g93e51e140
Satellite tracker/SDRangel control did not load the preset that I had set for the satellite when it became visible. Speech is working, as it announced the satellite becoming visible.
I closed the SSB demod that was running and opened APT. Satellite tracker was already running.
I set the frequencies and pressed play. SDRangel quit with this error:
2022-05-28 12:21:39.674 (D) APTDemodImageWorker::calcCoord: No TLE for satellite. Is Satellite Tracker running?
Segmentation fault

I restarted SDRangel, but it crashed again. The next time I ran SDRangel, it did not quit with Segmentation fault and I received the satellite.

I can provide more debug data if you tell me what and how to get it.

Would be useful if you could let us know exactly which demods you have open. A screenshot might help.

If you want to debug, you can do:

gdb /path/to/sdrangel
run

Then when it crashes

info stack 

And copy and paste the output here.

The demods were SSB or DSD. Either one will do it. NFM may occasionally cause the crash, but the satellite presets included that.

I can try the debug info when I have time.

I ran SDRangel 7.2.1-8-g93e51e140 under debug with the usual switches and to my surprise, it worked much better than it had been working. The only problem was that the spectrum/waterfall display froze.

gdb /opt/install/sdrangel/bin/sdrangel
run --soapy --fftwf-wisdom ~/.config/f4exb/fftw-wisdom

Was listening to SSB, when NOAA 18 became available.
SSB closed and APT opened.
ISS became available while NOAA 18 was visible. APT closed and NFM opened.
After ISS was no longer available, NFM closed and NOAA 18 opened APT again and received the satellite.

I received NFM and DSD for about 30 minutes.

I changed to SSB demod and closed NFM, but I left DSD Demod running. DSD Constellation did not freeze, but after about 30 minutes, the spectrum and waterfall display froze with SSB demod still receiving a signal.
I quit SDRangel and typed info stack.

There are no more satellites tonight.

Later, without gdb, I received with SSB demod while DSD demod was running. After about 20 minutes, the DSD constellation display froze, but it seemed to be receiving.

For some reason, SDRangel have been behaving much better that it had been.
In the past, 6.19 and newer crashed more often than not when Satellite tracker loaded a satellite preset.

V7 crashed frequently before I installed gdb. One strange thing that happened is that DSD demod constellation display never froze while running under gdb, but often did without gdb.

With that in mind, I booted up a Raspberry Pi OS with SDRangel 6.20.2. It does not have gdb installed.
With SDRangel 6.20.2, I had Satellite tracker, Maps, NFM, DSD running. Added SSB, there was no sound. Tried to close SSB and SDRangel froze. Force quit and restarted SDRangel and it happened again. Added SSB before hitting play and starting Satellite tracker and SSB works.
With those demods running, Satellite tracker loaded APT and NFM, spoke the message, then froze on satellite acquisition.
The terminal was rapidly displaying:

After this, cannot start SDRangel:
[ERROR] ReleaseDevice Error: sdrplay_api_ServiceNotResponding

I hope this is useful.

SDRangel 7.2.1-8-g93e51e140 running under gdb:
gdb /opt/install/sdrangel/bin/sdrangel
run --soapy --fftwf-wisdom ~/.config/f4exb/fftw-wisdom
Note: I restarted SDRangel and ran it with the same configuration. The crash happened again, the same way. I have that data also.

Had been receiving NFM and DSD.
NOAA 15 became visible and it received the satellite image.
Durng this time, NOAA 19 became visible, but NOAA 15 continued to be received.
When NOAA 15 was no longer visible, SDRangel had a Segmentation fault, probably when switching to NOAA 19, which was still visible.

I kept this terminal output, including info stack near the end:

The crash there appears to be in the APT demodulator - you might want to try running without that demod for now.

Thanks for looking at this. I hope that you will fix this when you have time.
The trouble seems to have started after v6.18.1.
I still love SDRangel.
