There was a problem hiding this comment.
Did you keep the beginning of the error message identical to keep compatibility?
If not, then it could be easier to read if it was like bad crc32 {got value} for file {name}, expected {expected value}. For now it’s slightly unpleasant to read about bad value, expected, expected, bad.
