Hi,

I got this error on the example below.

NVFORTRAN-F-0000-Internal compiler error. interf:new_symbol, symbol not found     625  (mod_test@smd_test.F90: 3)
NVFORTRAN/x86-64 Linux 21.7-0: compilation aborted

nvfortran -g -c mod_1.F90
nvfortran -g -c mod_1@smd_1.F90
nvfortran -g -c mod_2.F90
nvfortran -g -c mod_2@smd_2.F90
nvfortran -g -c mod_test.F90
nvfortran -g -c mod_test@smd_test.F90

mod_1.F90:

MODULE MOD_1

    IMPLICIT NONE

    INTERFACE PRC
        MODULE PROCEDURE :: PRC_1
    END INTERFACE PRC

    INTERFACE
        MODULE FUNCTION PRC_1(INPUT) RESULT(OUTPUT)
            IMPLICIT NONE
            REAL, INTENT(IN) :: INPUT
            REAL             :: OUTPUT
        END FUNCTION PRC_1
    END INTERFACE

END MODULE MOD_1

mod_1@smd_1.F90:

SUBMODULE(MOD_1) SMD_1

    IMPLICIT NONE

CONTAINS

    MODULE FUNCTION PRC_1(INPUT) RESULT(OUTPUT)
        IMPLICIT NONE
        REAL, INTENT(IN) :: INPUT
        REAL             :: OUTPUT
        OUTPUT = INPUT
    END FUNCTION PRC_1

END SUBMODULE SMD_1

mod_2.F90:

MODULE MOD_2

    IMPLICIT NONE

    INTERFACE PRC
        MODULE PROCEDURE :: PRC_2
    END INTERFACE PRC

    INTERFACE
        MODULE FUNCTION PRC_2(INPUT) RESULT(OUTPUT)
            IMPLICIT NONE
            REAL, INTENT(IN) :: INPUT
            REAL             :: OUTPUT
        END FUNCTION PRC_2
    END INTERFACE

END MODULE MOD_2

mod_2@smd_2.F90:

SUBMODULE(MOD_2) SMD_2

    IMPLICIT NONE

CONTAINS

    MODULE FUNCTION PRC_2(INPUT) RESULT(OUTPUT)
        IMPLICIT NONE
        REAL, INTENT(IN) :: INPUT
        REAL             :: OUTPUT
        OUTPUT = INPUT
    END FUNCTION PRC_2

END SUBMODULE SMD_2

mod_test.F90

MODULE MOD_TEST

    USE MOD_1
    USE MOD_2

    IMPLICIT NONE

    INTERFACE
        MODULE FUNCTION PRC_TEST(INPUT) RESULT(OUTPUT)
            IMPLICIT NONE
            REAL, INTENT(IN) :: INPUT
            REAL             :: OUTPUT
        END FUNCTION PRC_TEST

    END INTERFACE

END MODULE MOD_TEST

mod_test@smd_test.F90

SUBMODULE(MOD_TEST) SMD_TEST

    IMPLICIT NONE

CONTAINS

    MODULE FUNCTION PRC_TEST(INPUT) RESULT(OUTPUT)
        IMPLICIT NONE
        REAL, INTENT(IN) :: INPUT
        REAL             :: OUTPUT
        OUTPUT = INPUT
    END FUNCTION PRC_TEST

END SUBMODULE SMD_TEST

The problem disappears

  • if MOD_1 and MOD_2 are not used in MOD_TEST or
  • if the use statements in MOD_TEST are moved inside the MODULE FUNCTION PRC_TEST or
  • if generic interfaces PRC in MOD_1 and MOD_2 don’t have the same name.

Thanks AliG. I’ve filed a problem report, TPR #30461, and sent it to engineering for review.

Hi Mat

The problem still persists with version 22.2-0.

NVFORTRAN-F-0000-Internal compiler error. interf:new_symbol, symbol not found     625  (mod_test@smd_test.F90: 3)
NVFORTRAN/x86-64 Linux 22.2-0: compilation aborted

I would like to ask if there is a plan to solve this problem?

Thanks

Ali

Hi Ali,

Apologies, but it doesn’t seem like there’ been any movement on this one. Let me ping the compiler engineering manager to see if we can raise it’s priority, especially given the age of the issue.

Thank you very much.

Hi AliG,

FYI, TPR #30461 has been fixed in our 22.5 release.
