The above example in just one case where 'aid' can accept a null value.
That's not a null. It's a zero-length string.
I've found this is a feature of 7.3 to not treat a empty string as a NULL integer type. Silly lazy me.
As it turned out it relatively trivial to fix the offending statements on the few occasions where it has been valid to do this.
Consider this a non-issue.
