Hi there, Initialising pjsip 2.4 (pjsua_create) on iPhone 6, iOS 9 beta 3, arm64. (only this combination) Even the demo app crashes. iPhone 6 with armv7 is fine, iPhone 6 with iOS 8.4 is fine, iPhone 5s with iOS 9 arm64 is fine. Our year old version on the store crashes as well, it might be an OS issue. Humpf. Anyone else experiencing the same issue? * thread #10: tid = 0x7c013, 0x000000019af7a364 libsystem_pthread.dylib` *pthread_mutex_init* + 260, stop reason = EXC_BAD_ACCESS (code=257, address=0x1468683e4) * frame #0: 0x000000019af7a364 libsystem_pthread.dylib`pthread_mutex_init + 260 frame #1: 0x000000010008dae4 ipjsua`init_mutex + 168 frame #2: 0x000000010008e748 ipjsua`pj_mutex_create + 116 frame #3: 0x00000001000ebbf8 ipjsua`pjsip_endpt_create + 320 frame #4: 0x000000010012153c ipjsua`*pjsua_create* + 820 frame #5: 0x0000000100087514 ipjsua`app_init + 72 at pjsua_app.c:1292 frame #6: 0x0000000100086f00 ipjsua`pjsua_app_init(cfg=0x00000001001a0c38) + 56 at pjsua_app.c:1885 frame #7: 0x00000001000756f4 ipjsua`-[ipjsuaAppDelegate pjsuaStart](self=0x0000000145d77510, _cmd=0x0000000100157f77) + 280 at ipjsuaAppDelegate.m:111 frame #8: 0x0000000186b3e674 Foundation`__NSThread__start__ + 984 frame #9: 0x000000019af7bb18 libsystem_pthread.dylib`_pthread_body + 156 frame #10: 0x000000019af7ba7c libsystem_pthread.dylib`_pthread_start + 156 -------------- next part -------------- An HTML attachment was scrubbed...
