           Summary: [sh4] JavaScript engine randomly crashes
           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: jbriance at cisco.com


This uncommon case is seen when a flushConstantPool occurs in movlMemRegCompact.
As in this case a branch opcode and the constant pool are put before the movlMemRegCompact, the branch itself is patched when calling repatchCompact instead of the mov instruction, which is really bad.
