Segfault when connecting via SoapySDRServer

[andrewpile]

I've built SoapySDR from source with the new libairspyhfSupport.so:

However when using it via SoapySDRServer it segfaults.

Segmentation fault

The initial accept connections appear to be from the mdns connections, the crash only happens when actually activating the SDR. I tested this with Gqrz and openwebrx.

Let me know what else I can provide, if anything. I tried to get some specifics with gdb but it didn't reveal anything useful.

Thanks for testing and the report @andrewpile! I will take a look as soon as I can.

This was due to SoapySDRServer wanting to read very small buffers size. I have fixed that now. SoapySDRServer should not have segfaulted though. That's another bug we have to look into.

Connection to SoapySDRServer, at least for me, now appears fine when connected to from Cubicsdr and SigDigger. I was able to tune and use the radio without a segmentation fault.

Hey I can confirm this is working for me as well, thanks!
