Re: SpiderMonkey 52 JS tests fail on s390x

[Jason Orendorff]

Charles,

Sorry for the lack of response here. Yes, these test are real, and they
should pass. Without looking closer, I can add that problems with typed
arrays and ArrayBuffer (which all of these are) are especially worrying
from a security/crash-safety perspective.

All of these tests happen to use BYTES_PER_ELEMENT. Can you run the JS
shell you built manually? What's the value of
Float64Array.BYTES_PER_ELEMENT?

Consider getting an account on bugzilla.mozilla.org and filing this as a
bug.
