Problem summary

  • PROBLEM DESCRIPTION:
    The compiler encounters an internal error when calling a
    Fortran procedure with an assumed-size or explicit shape
    argument that also has an optional character argument with
    assumed-length.  For example:
    
    test.f90:
    contains
    
    SUBROUTINE t1(afull, mat_label)
    implicit none
    real :: afull(*)
    character(*), optional :: mat_label
    END SUBROUTINE
    
    SUBROUTINE t2()
    implicit none
    real, pointer   :: U_full(:)
    
    call t1(U_full)
    
    END SUBROUTINE
    
    END
    
    USERS AFFECTED:
    Users who have procedures with OPTIONAL assumed-length
    character arguments.
    

Problem conclusion

  • Fixed the interface to handle optional assumed-length character
    dummy arguments that are not present.
    

Temporary fix
