https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220767 --- Comment #6 from Jason Evans <jasone@FreeBSD.org> --- I don't have any specific ideas as to why this is happening. Bootstrapping jemalloc on FreeBSD is really tricky, because pthreads mutexes use malloc, = and jemalloc has to jump through hoops to initialize its mutexes in multiple phases. It looks like beignet depends on the libpthread-stubs package. Is it possi= ble that the stubs don't sufficiently stub out the libc-internal hooks that jemalloc uses to bootstrap? Here's a list of pthreads-related symbols jema= lloc depends on (generated by building stand-alone jemalloc): _pthread_mutex_init_calloc_cb je_pthread_create_wrapper pthread_cond_init pthread_cond_signal pthread_cond_timedwait pthread_cond_wait pthread_create pthread_create_fptr pthread_join pthread_mutex_lock pthread_mutex_trylock pthread_mutex_unlock pthread_sigmask --=20 You are receiving this mail because: You are the assignee for the bug.=
