I agree that the udf must catch exceptions and treat them, but i do not
understand that one udf crash the engine and that there is nothing to do to
avoid that.

I do not say to free the memory allocated by the udf, or doing work that the
udf do not do, i try to transmit that firebird should be rock solid and an
exception in a udf does not have to crash the engine. It is just a thought,
because one customer that uses other engines (oracle, postgre, sql server),
when i explained that behaviour with firebird didn't understantd this
reasoning.

Does some one have information if other engines have the same performance?

Regards.
Jesus
