Another reason for X'80000000' would be a null last entry in a variable
length parameter list. And I could imagine someone not checking for
that. (A null entry at the end of a variable list? Who would do THAT?)
And if the code is in a seldomly executed path in seldomly invoked error
recovery code it could have gone unnoticed for a long time.

That's not applicable here, Pat. Look at the OP.
