Hi Benny, I tried out your suggestion but futile. See http://pastebin.mozilla.org/347117 I included this snippet in each function call. 1. static pj_thread_desc desc; 2. static pj_thread_t * thread; 3. #define REGISTER_THREAD() \ 4. if(!pj_thread_is_registered()) {\ 5. pj_thread_register(NULL,desc,&thread);\ The static variables won't get called (i.e. resulting in an error) when placed in a global scope. Otherwise, the integration is OK but I can't re-register once I de-register, my browser crashes. I mean that is when I get this error: firefox-bin: ../src/pj/os_core_unix.c:276: pj_thread_register: Assertion `thread->signature1 != 0xDEAFBEEF || thread->signature2 != 0xDEADC0DE || (thread->thread == pthread_self())' failed.
