           Summary: Calls to weakCompareAndSwap() compile successfully but
                    crash at runtime when COMPARE_AND_SWAP is not enabled
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mitz at webkit.org
                CC: fpizlo at apple.com


By definition, weakCompareAndSwap crashes if built when !ENABLE(COMPARE_AND_SWAP). It would be safer for the code to fail to compile in this case.
