This NSLayoutConstraint is being configured with a constant that exceeds internal limits. A smaller value will be substituted, but this problem should be fixed. Break on BOOL _NSLayoutConstraintNumberExceedsLimit(void) to debug. This will be logged only once. This may break in the future.

^ AutoLayoutで遊んでたらこういうログを見た。 OS バージョンで閾値は異なるようです。
