           Summary: Exceptions not thrown correctly from DFG JIT on 32bit
           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


Arguments for lookupExceptionHandler are not setup correctly.  In the case of ARMv7 we rely on lr being preserved over a call, this in invalid.  On x86 we don't should be poking the arguments onto the stack!
