I added one case where this changes behavior in 8bdcd0a96e65557c8c3bf506d186c49002db6463

Not looked closely at it, but I think previously the code should only retry with runtime checks if there is an unknown dependence with non-constant distance.

Now we will always retry with runtime checks, even if we had a non-constant distance that isn't unknown?
