The warning describes a problem with data generated internally, not a
problem with the user input.  This is definitely a bug.  It is not
necessarily a regression since it is conceivable that 2.12.3 just did
not diagnose the problematic situation.  So it will require some
analysis by a developer to decide whether this is also a regression.
