Local fix

  • This issue can be avoided with the option -Xjit:optLevel=cold.
    Note that this can incur significant performance degradation.
    

Problem summary

  • The JIT compiler logic called "induction variable analysis" was
    missing a check.  This resulted in dereferencing a bogus
    pointer.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR4
    6.0.1 SR5
    .
    The necessary check was added to induction variable analysis.
    

Temporary fix
