Maybe it should be void *cb_buf[]

CID 1454761:  Incorrect expression  (SIZEOF_MISMATCH)
/src/lib/err/backtrace.c: 107 in unlock_cb_buf()
101     }
103     /** Unlock the static stack pointer buffer. */
104     static void
105     unlock_cb_buf(void *cb_buf)
106     {
   CID 1454761:  Incorrect expression  (SIZEOF_MISMATCH)
   Passing argument "cb_buf" of type "void *" and argument "2048UL /* 256 * sizeof (void *) */" to function "memset" is suspicious.
107       memset(cb_buf, 0, SIZEOF_CB_BUF);
108       pthread_mutex_unlock(&cb_buf_mutex);
109     }
