…al_op Problem: When a query contains large number arithmatic operations (e.g. addition) on numbers, it can trigger deep recursion leading to a stack overrun and crashing the server. Currently, the server checks for stack overruns only during `fix_fileds` time and not during the execution of the query. Fix: Introduces a stack overrun check druing the execution of query to prevent crash during the execution time.
