Sorry for the ambiguity -- I have no evidence of miscompilation. My
"just BTW" paragraph was a reaction to the memory of the last couple
of times Noah and I wasted hours chasing red herrings on this system,
which is pretty demotivating when looking into an unexplained failure.
On a more practical note, I don't have access to the BF database right
now. Would you mind checking if "latch already owned" has occurred on
any other animals?
