For me it's 100% reproducible in my app. What can I do to fix this or to help you to fix this? Under what circumstances can this assertion be hit? I don't do anything special with pjsua-lib from my app, I don't make any pjsip function calls from secondary threads. I made a debug build of pjsip. Here's the backtrace when assertion was hit. Assertion failed: (thread->signature1 != 0xDEAFBEEF || thread->signature2 != 0xDEADC0DE || (thread->thread == pthread_self())), function pj_thread_register, file ../src/pj/os_core_unix.c, line 405. Program received signal: ?SIGABRT?. Data Formatters temporarily unavailable, will re-try after a 'continue'. (Not safe to call dlopen at this time.)
