Local fix

  • -Xjit:disableGlobalVP
        As with any option that disables an optimization, this can
    cause the jit compiler to generate slower code.
    

Problem summary

  • The jit compiler's Global Value Propagation optimization was
    made more aggressive in an attempt to improve the performance of
    the generated code, but the changes made were not correct in all
    cases.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR4
    6.0.1 SR5
    .
    The new Global Value Propagation logic was disabled, thereby
    restoring the jit compiler's older, correct behaviour.
    

Temporary fix
