Fascinating.  That's a pretty serious regression.  Keith, do you remember what we've done with subarray?

Arthur, are you OK with your http://zenmumbler.net/bugs/array_creation.html benchmark being included in our JSRegress suite?  It's a suite of miscellaneous benchmarks that we run regularly.  That way, after we fix this bug, this would help catch future regressions.

The easiest way to do this is if you uploaded it as an attachment to bugzilla.  That's the best kind of implicit approval that you're OK with this code being in WebKit.

You are receiving this mail because:
You are the assignee for the bug.
