Thank your for catching it. I did actually read all the comments. The trouble
is that there are several test cases here and I missed the one in the second
half of comment #6 (the first half of the comment doesn't seem to apply
anymore, at least not on x86_64).
(In reply to Bill Seurer from comment #13)
You're right, the test fails on powerpc64le (though as far as I can see not on
any other target with reported test results). It seems like a useful test
despite the above so rather than backing it out entirely I could disable it for
powerpc64le until it's analyzed.
Bill (Seurer or Schmidt), does either of you have a preference for how to
handle the failure?
