message:
MDEV-16506 CTE with overflow of integer type returns wrong results
When adding rows to the table defined by a recursive CTE the method
select_unit::send_data() must check weather new generated rows
contain out of range data. If so it should report an error. Otherwise
the truncation of data can cause endless generation of identical
groups of rows.
