Well your original backtrace showed it dying at line:
lib/util/genrand.c:37
Which is:
30 static void open_urandom(void)
31 {
32 if (urand_fd != -1) {
33 return;
34 }
35 urand_fd = open( "/dev/urandom", O_RDONLY,0);
36 if (urand_fd == -1) {
37 abort();
38 }
39 smb_set_close_on_exec(urand_fd);
40 }
the abort(), which gets triggered if urand_fd == -1
after open. So you'll need to debug that.
