Our app uses the pjsip library (version 2.3), but it's crashing when running on iOS 9 beta 3, apparently when attempting to create a mutex using pthread. Relevant stack trace:

Thread 11:

6   RingTo Production             0x00000001003a8d98 pj::Endpoint::libCreate() + 24

This looks like a bug in iOS itself, anyone encountered something similar?

Our app (build on iOS 8 SDK) also uses pjsip (version 2.4) and when running on a device with iOS 9 beta 3 we get the same crash.

Building the app and pjsip using iOS 9 SDK results in the same crash.

I installed beta 4 on my device and it seems to have fixed the issue. Can you confirm @silviud?
