Comment(by igloo):

 Replying to [comment:6 kili]:
 > Thanks. But is this really *one* Bug? There are the problems with non-
 determinisms, but I think that the CSE on inlined constants (like
 cBooterVersion and cProjectVersion) is a separate problem.

 I don't think that's a bug at all. You are compiling different source
 code, so it's entirely reasonable that the ABI should be different.

 If the ABI was otherwise stable then it might be worth trying to work
 around `cBooterVersion`'s value affecting the ABI, though.
