ok, I choose to add 'disable_warnings'.

I execute the statement twice here. 
Interestingly, in prepared statements mode the 'const' property of
the subquery is lost. This was suspicious enough for me to add a
separate test.

I don't know why. And since you're rewriting subqueries in 6.0, I
don't want to investigate more than I did (1 hour).
