Segmentation Fault after upgrade on void linux

["Ilias Clifton" <adilias3@xxxxxxx>]

Hi All,

 

I've been using pjsua on my void linux system for quite a while without issue. Unfortunately it's stopped working.

 

pjsau starts up ok, but as soon as I attempt to make or receive a call, I get a segmentation fault - Can someone assist in troubleshooting?

 

It appears to be audio device related. Audio works ok in other applications such as firefox and vlc.

 

  pjsua has been installed via the pjproject package via xbps.

 

dmesg and syslog report:

 pjsua[8940] general protection fault ip:7f268e92581d sp:7f268d88d0c8 error:0 in libc-2.30.so[7f268e7e9000+149000]

 

Void linux is a 'rolling release' and I do upgrade regularly - going back through the logs it looks as though linux kernel was recently update from 5.4-5.4.13_2 to 5.4.19_1, and then a few days later from 5.4.19_1 to 5.4.21_1

 

I can't see any recent updates to libc.

 

I tried uninstalling the pjproject package and compiling pjproject manually - I get the same issue with the compiled version.

 

I tried running pjsystest, and the the test wizard - it Segfaults when it tries to play the ring tone.
