@gatorsmile @HyukjinKwon @ajacques I'm seeing incorrect results from the
following simple projection query, given @jainaks test file:
```
select page.url, page from temptable
```
This is worrisome to me.
The failure scenario can probably be simplified further, and that will be
part of my investigation. However, I've just started digging deep into this,
and I have company coming over for the rest of the night in about half an hour.
I probably won't have a solid lead on or solution to this bug until tomorrow.
Does anyone else want to work on it?
