            Bug ID: 199523
           Summary: WKObject's minimum object alignment needs to be larger
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Macintosh
                OS: Other
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: saagarjha at apple.com

Got a warning when working on something unrelated: apparently some of the objects we wrap with WKObject require 16-byte alignment on my system (such as WebFrameProxy) but we are running its constructor on an 8-byte aligned address. I believe that changing minimumObjectAlignment to 16 should cover everything that we use, but I have a patch with something that's IMO more portable than a hardcoded number that I'll attach as soon as I can get around to it.
