I'm betting that something is rounding up to the next multiple of 8
bytes, and then something else is trying to fit the result in a short
integer. Dunno where though --- AFAIR, all the LO-related code uses
integer counts, and I can't think of a good reason for rounding off
to an alignment multiple either.
Can you pursue this further and identify the culprit? I have no time
for it at the moment.
