It was:

-       return ((test_bit(ATTR_STATUS, ct->head.set) ?
-               ct->status & IPS_SRC_NAT_DONE : 1) &&
-               ct->repl.dst.v4 !=
-               ct->head.orig.src.v4);

I thought it keeps checking even ATTR_STATUS is not set.
But it's ok not to apply, returning false in case of
ATTR_STATUS is not set.

Thanks,
