Hi Navis,

scope of this issue. Does this get triggered only in cases of using aliases
which end up mapping to the same value upon hashing
Hi, sorry for late reply.
As Chun Chen said, same hashcode would make this problem vivid. But it can
be happened whenever the appearing order in JOIN expression is different

Thanks.

I look at your patch and it's exactly the same place we are working on.
Thanks for your patch.

and attached patch for it.
It needs full test for confirmation but you can try it.
Thanks.
