[[
V does not have an [[ArrayBufferData]] internal slot
]]

We should use IsDetachedBuffer instead as is already done elsewhere.
Comment 2 Anne 2015-07-07 06:50:58 UTC 
You forgot to remove the [[ArrayBufferData]] check. See http://ecma-international.org/ecma-262/6.0/#sec-isdetachedbuffer in particular.
Comment 3 Cameron McCormack 2015-07-07 07:22:54 UTC 
IsDetachedBuffer asserts that [[ArrayBufferData]] exists, rather than checks-and-throws if it does not exist. So I think callers of IsDetachedBuffer need to ensure that the value passed to it is already an object with an [[ArrayBufferData]].
Comment 4 Anne 2015-07-07 08:07:02 UTC 
My bad.
