           Summary: It should be possible to create an inheritorID for the
                    global this object without crashing
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fpizlo at apple.com


The global this object has a structure that has a null global object. That makes sense since there is no one global object that the structure could be associated with. But what doesn't make sense is that this leads to the inheritorID structure created for objects that have the global this object as their prototype also having a null global object, which then results in hilarity and badness when any operation is performed on those objects that expects to be able to query the global object via the structure.
