seg fault using aispy + SoapySDR #35650

Closed neoklis closed 2 years ago

neoklis commented 2 years ago

System

AMD64 (Compulab FitPC4 computer)

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. 0x0000000000d2f520 in ?? () (gdb) bt

0 0x0000000000d2f520 in ?? ()

7 0x000000000040e5f9 in Append_Sample_Rates ()

8 0x000000000040adef in Device_Combobox_Changed ()

"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 I have no clear indications that my apps are to blame but I see that both SoapySDR and airspy libs are outdated versions.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

Hi

I manually installed the latest libairspy from airspy.com and the fault has cleared. Presumably the issue can be closed when the repository packages of libaispy are upgraded accordingly.

@neoklis did you install from master or from a release? There are some libusb fixes in master that are not yet in a release and we recently updated libusb.

neoklis commented 2 years ago

Well, I used the "Code" button in https://github.com/airspy/airspyone_host to download a zip file of the source code and the installed version is 1.0.11. I believe the Master branch is the default in the link above. I did not manually select a specific branch so it must be the Master version I used. There is also this comment: "Fixed the usb tear-down sequence" so its likely to do with our upgrade of libusb.
