           Summary: Crash on blogspot sites
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh PowerPC
               URL: http://cosmosamiga.blogspot.com/
        OS/Version: Other
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fabien.coeurjoly at wanadoo.fr


On a PowerPC machine, using JavascriptCore interpreter, browsing blogspot sites causes a crash. For instance, http://cosmosamiga.blogspot.com/ . Clicking once or twice the upper tabs is enough to trigger it.

>From the stack trace, the crash happens around throwError() in the exec->globalData().exception = error assignation. It seems ScopedChain()->globalData is in fact corrupted (most likely ScopedChain is already freed at that point).
