           Summary: Delay creating the PCVector until an exception is thrown
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: sam at webkit.org


Delaying the creation of the PCVector until an exception is thrown will save
about 2MB on membuster head.  This will require re-JITing to build the offset
mappings.
