Hi Ming, The stack trace shows the following calling sequence when a SIGSEGV : SEGV_MAPERR occurs: pjmedia_delay_buf_destroy pjmedia_conf_destroy pjsua_aud_subsys_destroy pjsua_media_subsys_destroy pjsua_destroy2 voip_destroy Valgrind indicated that app_config.pool was being accessed but it had been released. Thanks for the feedback. I shall investigate further :-) Warmest regards, Jeff On Fri, Apr 4, 2014 at 2:06 AM, Ming <ming at teluu.com> wrote: > Hi Jeff, > > app_config.pool should be the application's pool, which pjsua (or > pjsua_destroy()) should have no knowledge of.
