           Summary: Null name for host function can result in dereference
                    of uninitialize memory
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com


This is a recent regression in ToT, if the name passed to finishCreation of a host function is null, we are currently skipping the putDirect, which leaves memory uninitialized.
This patch reverts the aspect of the change that introduced the issue.  It might be better if functions that don't have a name don't have this property at all, but that's change should be separate from fixing the bug.
