during udf initialization. The bug is spotted while working on Bug 12713. If a user-defined function was used in a SELECT statement, and an error would occur during UDF initialization, this error would not terminate execution of the SELECT, but rather would be converted to a warning. The fix is to use a stack buffer to store the message from udf_init instead of private my_error() buffer.
