Check the size of trigger. Sometimes it show like this if the size reaches 64k.

Hi,

Recently I have found the error arithmetic exception, numeric overflow, or string truncation

string right truncation
At trigger 'XXXXX'

on different trigger or stored procedure.
The strange thing is that are not true, in the trigger or procedure there isn't any operation that coud produce this exception!

I "recompile" the trigger or procedure that are affected and the error disappear!..

It could be a bug in my relase of Firebird?
