This layout test fails on chromium webkit canary bot: fast/dom/prototype-inheritance.html Looks like http://trac.webkit.org/changeset/64141 causes this failure.
Hmm, are you sure that's what's causing it? Seems unlikely. Anyway, I will look tomorrow (I am in London and it's midnight right now). If you are certain that my change is the cause, please roll it out and I will fix it tomorrow.

If you are certain that my change is the cause, please roll it out and I will fix it tomorrow. Looks to me this is the cause. I did not manually run it to verify so not 100% sure. Here are the actual test results: ---- Make sure prototypes are set up using the window a property came from, instead of the lexical global object. On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". PASS inner.Array.isInner is true ... FAIL inner.IDBKeyRange.isInner should be true. Was false. FAIL inner.IDBKeyRange.constructor.isInner should be true. Was false. PASS inner.Image.isInner is true ... FAIL inner.Infinity.isInner should be true. Was false. FAIL inner.Infinity.constructor.isInner should be true. Was false. PASS inner.JSON.isInner is true
Andrei, I'm guessing this failure is why all this stuff is hand-written right now. There must be some subtle differences in semantics that matter. And/or you need to add it to the list of stuff it doesn't check. ....actually I think it's the latter. :-)
