to avoid problem with the new behaviour of new V8 BackingStore API. By

different.

Since there’s no protection in the binding I’d suggest some sort of comment in the test to discourage new check()s being added in the future that result in duplicate base addresses.

The daily build failure predates this PR, so maybe is fixed.

@sam-github I believe it is -- it's failing the same check and the underlying issue that was fixed is not AIX specific.
