+Subject: [PATCH] Continue to back away from the LEFT JOIN optimization of
+ check-in [41c27bc0ff1d3135] by disallowing query flattening if the outer
+ query is DISTINCT.  Without this fix, if an index scan is run on the table
+ within the view on the right-hand side of the LEFT JOIN, stale result
+ registers might be accessed yielding incorrect results, and/or an
+ OP_IfNullRow opcode might be invoked on the un-opened table, resulting in a
+ NULL-pointer dereference.  This problem was found by the Yongheng and Rui
+ fuzzer.
