On FreeBSD stable12, the testparm utility of a local build of samba413 accesses an invalid curthread as returned from _get_curthread(). Breakpoint 2, thr_malloc_lock (curthread=0x802c057d0) at lib/libthr/thread/thr_malloc.c:64 64 if (curthread == NULL) (gdb) bt #0 thr_malloc_lock (curthread=0x802c057d0) at lib/libthr/thread/thr_malloc.c:66 #1 __thr_calloc (num=1, size=96) at lib/libthr/thread/thr_malloc.c:88 #2 0x00000008014330a3 in mutex_init (mutex=0x80106f008, mutex_attr=<optimized out>, calloc_cb=<optimized out>) at lib/libthr/thread/thr_mutex.c:295 #3 __Tthr_mutex_init (mutex=0x80106f008, mutex_attr=<optimized out>) at lib/libthr/thread/thr_mutex.c:395 #4 0x000000080203ef2c in gnutls_system_mutex_init () from /usr/local/lib/libgnutls.so.30 #5 0x0000000802038773 in _gnutls_global_init () from /usr/local/lib/libgnutls.so.30 #6 0x0000000802038b37 in lib_init () from /usr/local/lib/libgnutls.so.30 #7 0x000000080103564d in ??
