Error description

  • When constructing a multi-variate array with an implied-do
    constructor, the compiler is generating incorrect values.  For
    example, the following implied-do constructor:
    
    INTEGER, PARAMETER :: indices(36) &
      = (/ ((((16 + i + j*3 + k*12 + l*48, i=0,1), &
    j=0,2), k=0,2),l=0,1) /)
    
    , gives the following output:

    Expected Output:
    
       16   17   19   20   22   23
       28   29   31   32   34   35

    =============
    Actual Output:
    
       16   17   22   23   28   29
       18   20   24   26   30   32
       24   27   30   33   36   39

Local fix

Problem summary

  • PROBLEM DESCRIPTION:
    The Fortran compiler may incorrectly process long ac-value
    expressions in an array constructor.  This may cause
    applications to produce incorrect results.
    
    USERS AFFECTED:
    Users may encounter this problem if their application contains
    array constructors involving long expressions as ac-values.
    

Problem conclusion

  • The problem has been fixed.
