            Bug ID: 154874
           Summary: DFG intrinsics and operations play fast and loose with
                    the lexical global object
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: fpizlo at apple.com

Lots of native code says "exec->lexicalGlobalObject()".  This is meaningless when we're called directly from DFG- or FTL-generated code.
