I tried an even more simple test (create table dummy (a varchar2(2))), and
was not able to reproduce the problem. Still investigating, but I am very
suspicious. Another anomaly is that running my original sql with a 10053 did
not produce a trace file (statistics_level = all). The last, very simple
test did, however.

I filed a bug with Oracle. Apparently, bind buffers are not peeked when you set statistics_level = ALL in At least, not for my simple tests.

I was using statistics_level = all because it makes Cardinality Feedback
so much simpler (query 2 dictionary tables, as opposed to ripping apart
10046 and 10053 traces). So much for that idea....
