Problem summary

  • Internal testing has uncovered a functional bug due to improper
    global register allocation. The symptom could have been anything
    really but in this case it happened to cause an exception. The
    problem would appear as a clobbering of the value in some global
    register with a new value (prematurely put into the register).
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR5
    6.0.1 SR6
    .
    The JIT has been updated to eliminate the problem with global
    register allocation.
