Nice test case Alberto.  The whole thing seems familiar to me too - I have a 
feeling if/when we get to bottom of this it will be a "Doh!" moment.  I wonder 
if Jonathan Lewis visits this list anymore - I bet he'd know the answer but I 
don't recall seeing his name pop up here for a while.

Ian, it would be interesting to see your results from running Alberto's test 
case against your database.

I think Ian might want to try; the following test case shows that
the CBO, in that version, does seem to peek for the binds "through" a
date function
