> A while ago we ran into a stack overflow in the parsing with one our query. It's still an issue (tested this morning) so we decided to report it as a bug.
> If run the query in attachment you get a stack overflow error probably because there to many where. Granted, this query isn't pretty, but still the parser shouldn't stack overflow.
> FYI, the where clause where used for partition pruning.
