Comment (by trommler):

 Replying to [comment:10 admock]:
 > I bisected containers and the bad commit is
 cfb136731bc5c182e005b21a2dd857fd8c9694df.  I looked at the diff but I
 don't see how it could cause this.
 Thanks. I had started bisection as well, but my PowerMac is quite slow :-(

 I suspected that commit could be the culprit. Something in the
 implementation of an unboxed array could be endian sensitive. I think I
 saw some changes regarding unboxed arrays happen recently.

 But first I will have a look at changeset:ec22f7dd again, which is the
 commit that caused #15399 and that is only partially fixed. My plan is to
 cherry-pick cfb126 in containers
 and build at changeset:ec22f7dd and the previous commit.
