I think this is the sequence of exceptions that will cause such an error:
try
{
    klass a;
    try
    {
        klass a;
        try {
            klass a;
            throw new klass();
        }
        catch (int) {}
    }
    catch (void*)
    {
        klass a;
        throw;
    }
}
catch (void*)
{
    klass a;
}
In this case unwind_help[0] is uninitialized causing incorrect local_unwind.
