To Artifact [889cba075c]:

• File src/runtime/class.m — part of check-in [ede088a30d] at 2019-04-14 13:35:38 on branch trunk — runtime: Match Apple's +[initialize] behavior

  This now calls +[initialize] several times on the same class if it is
  unimplemented in one or more of the classes in the chain, to match the
  behavior of the Apple runtime. While the behavior before was safer, it
  can lead to testing against the ObjFW runtime and everything working,
  but then failing when trying to use it with the Apple runtime. (user: js, size: 21133) [annotate] [blame] [check-ins using]
