addr_ = (nil) is strange, but it may be just optimised out. Compiling
with -g -O0 helps with this kind og thing (gcc).
But yes, it looks more like a problem with SSL. The call should not fail
in this fashion. The arguments look like they cannot be messed up:
unsigned char rand_buf [16];
int ret = RAND_bytes (rand_buf, sizeof rand_buf);
