I know we really should move to 8.1.3, but I haven't gotten to it yet.
We're on a build from the 8.1 stable branch as of February 10th, with a
patch to allow ANSI standard interpretation of string literals. (So
this is 8.1.2 with some 8.1.3 changes plus the string literal patch.)

If there are any changes in that time frame which might affect this
issue, I could deploy a standard release and make sure that I see the
same behavior. Let me know.
