EXC_BAD_ACCESS in hostAddressFamily - m:897

[Lyle42]

Very rarely, but more than once, I'm getting an EXC_BAD_ACCESS crash in the hostAddressFamily{} method.

I believe that self.hostAddress is the culprit:

• (sa_family_t)hostAddressFamily {
  sa_family_t result;

  result = AF_UNSPEC;
  if ((self.hostAddress != nil) && (self.hostAddress.length >= sizeof(struct sockaddr)) ) {
  result = ((const struct sockaddr *) self.hostAddress.bytes)->sa_family; // crash here ***, EXC_BAD_ACCESS, KERN_INVALID_ADDRESS at 0x0000000000000001
  }
  return result;
  }
