Another report came to me privately that had tracked it down in the
other direction -- building -CURRENT from an earlier 12 -- that
pointed directly at a bug in crunchgen on -CURRENT. I've committed the
fix in r366466, you will want to update to that world or at least
rebuild+reinstall crunchgen with that fix.
