Closed issue by neoklis on void-packages repository

https://github.com/void-linux/void-packages/issues/35650

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System
AMD64 (Compulab FitPC4 computer)
* package:  airspy-1.0.10_1

### Expected behavior
Should work with Airspy SDR
### Actual behavior
Segmentation fault
### Steps to reproduce the behavior
Problem started recently, possibly after and update of Void. When running any application
that uses an Airspy SDR in conjunction with SoapySDR, SoapyAirspy  and libairspy then a seg fault occurs:

Thread 1 "sdrx" received signal SIGSEGV, Segmentation fault.

"sdrx" is an SDR receiver client I wrote myself. Its been working well for a long time. The fault occurs with another app I wrote, "glrpt", which was also working well for some years.

The fault doesn't occur when using the same apps with RTL-SDR devices so it seems to be an issue with airspy libs. I have no clear indications that my apps are to blame but I see that both SoapySDR and airspy libs are outdated versions. 

My thanks in advance
