           Summary: Uninitialized member causes crash when DFG JIT is not
                    enabled.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: peavo at outlook.com


The data member sizeOfLastScratchBuffer in the VM class is only initialized if DFG JIT is enabled, even though it's defined regardless.
This causes an early crash on Windows, which doesn't have DFG JIT enabled.
