Problem summary

  • USERS AFFECTED:
    Users who compile with -qcheck=all with optimisation level 2 or
    higher may be affected by this issue.
    
    PROBLEM DESCRIPTION:
    An internal optimization tries to replace loads and stores with
    update forms and so needs to rewrite them.
    It was not taking into account the possibility of an unknown
    number of trap bags on the address
    specification, ie, one for each dimension that was used for
    bounds checking.
    

Problem conclusion

  • The internal optimization has been modified to handle the above
    scenario.
    

Temporary fix
