Thank you for the bug report.
However, your report is not helpful in finding and fixing the problem.
If possible, please send the following information:
(1) The complete stack trace - not just the first 18 levels of the
stack. This is especially important for a stack-overflow error.
(2) The text of the SQL statement that caused the stack overflow.
(3) The database schema
Thanks.
