Or does it come back? If it's a one-time dependency issue that is because some header dependency addition that the automatic dependency generator hadn't caught, that might explain a bisection failure too: once the file happens to get rebuilt (and the dependencies re-done), it starts working even though the "happens to be rebuilt" had nothing to do with the original bug.
