Hello all,
I have successfully compiled and installed pjsip 2.7.2 on a Raspberry Pi with ARM Linux. But the problem I have now is that pjsip is permanently crashing with a segmentation fault. The segmentation fault even happens when I am using the pjsua demo application, so I am assuming that it cannot be possible related to wrong use of the pjsip library. The poblem occurs if I try to run the PJSUA demo app (located in the subdirectory "pjsip-apps/bin") with the following command line:
./pjsua-armv7l-unknown-linux-gnueabihf --realm="..." --username="..." --password="..." "sip:**701@xxxxxxxxx"
In order to find out where exactly the segmentation fault occured, I have compiled PJSIP with debug symbols and ran the pjsua app with GDB. This gave me the following stack trace:
Thread 3 "pjsua-armv7l-un" received signal SIGSEGV, Segmentation fault.

I also tried to run the pjsua demo app with Valgrind, but this failed as Valgrind hung up during the execution. Does anyone have an idea what the root cause of this problem could be or what I could still do to to find out the rot cause of the issue? I am a bit lost as I don't know the code....
The output of the pjsua demo app up to the point of the crash looks unsuspicious to me. I have pasted it below this mail for your reference.
I appreciate any help!
Best regards,
Christian
