[Bug fortran/36316] New: type mismatch in binary expression caught by verify_gimple

["toon at moene dot indiv dot nluug dot nl" <gcc-bugzilla@gcc.gnu.org>]

The following module definition:

MODULE YOMCAIN

IMPLICIT NONE
SAVE

TYPE distributed_vector
REAL, pointer :: local(:)
INTEGER       :: global_length,local_start,local_end,nchnks
END TYPE distributed_vector

INTERFACE ASSIGNMENT (=)
MODULE PROCEDURE assign_dv_dv
END INTERFACE

INTERFACE OPERATOR (*)
MODULE PROCEDURE multiply_dv_dv
END INTERFACE

CONTAINS

SUBROUTINE assign_dv_dv (handle1,handle2)

!         copy one distributed_vector to another

TYPE (distributed_vector), INTENT(IN)    :: handle2
TYPE (distributed_vector), INTENT(INOUT) :: handle1

handle1%local(:) = handle2%local(:)

RETURN
END SUBROUTINE assign_dv_dv

FUNCTION multiply_dv_dv (handle1,handle2)

!         multiply two distributed_vectors

TYPE (distributed_vector), INTENT(IN) :: handle2
TYPE (distributed_vector), INTENT(IN) :: handle1
REAL, DIMENSION(handle1%local_start:handle1%local_end) ::multiply_dv_dv

multiply_dv_dv = handle1%local(:) * handle2%local(:)

RETURN
END FUNCTION multiply_dv_dv


SUBROUTINE CAININAD_SCALE_DISTVEC ()
TYPE (distributed_vector) :: PVAZG
TYPE (distributed_vector) :: ZTEMP
TYPE (distributed_vector) :: SCALP_DV

ZTEMP = PVAZG * SCALP_DV
END SUBROUTINE CAININAD_SCALE_DISTVEC
END MODULE YOMCAIN

draws this error message when compiling with a recent 4.4.0 gfortran:

a.F90: In function 'caininad_scale_distvec':
