I can confirm this with a local debug build of r38680.

I thought this might be a reparsing bug, but it works fine in r38635, the revision that introduced reparsing.

I can verify that this regresses in r38652, the introduction of polymorphic caching of prototype accesses.

Comment on attachment 25373 [details] Ooops Add a reference to this bug in the ChangeLog, and add a reproducibly failing layout test for this situation to fast/js/pic. Assuming you do that, r=me.

Gavin, hopefully you can get around to making a test and landing this soon. This bug makes WebKit unusable for a lot of people.
