           Summary: CodeBlock::needsFullScopeChain not always set for global
                    code
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: cwzwarich at uwaterloo.ca

If a unit of global code doesn't define any functions, the associated CodeBlock
does not have needsFullScopeChain set. Since we use this to test for copying
local variables to temporaries when necessary, it leads to incorrect behaviour.
I will post a test case in the next post.
