Summary: Fortran 2003 - Type Bound Procedure Error - Type
Mismatch
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ortp21@gmail.com
The following error is produced by the example typeboundprocedure.f95, pasted
below:
Error
----------------------------------------------
typeboundprocedure.f95:46.12:
print *, b_type_instance%sizeReturn()
1
Error: Type mismatch in argument 'a_type_' at (1); passed TYPE(b_type) to
CLASS(a_type)
----------------------------------------------
I have tested the same example using the Intel Fortran Compiler 11.1 on Linux
and it compiles without error.
Compiled using:
gfortran -c typeboundprocedure.f95
typeboundprocedure.f95
----------------------------------------------
module A
implicit none
type :: a_type
private
integer :: size = 1
contains
procedure :: sizeReturn
end type a_type
contains
function sizeReturn( a_type_ )
implicit none
integer :: sizeReturn
class(a_type) :: a_type_
sizeReturn = a_type_%size
end function sizeReturn
end module A
module B
implicit none
type :: b_type
private
integer :: size = 2
contains
procedure :: sizeReturn
end type b_type
contains
function sizeReturn( b_type_ )
implicit none
integer :: sizeReturn
class(b_type) :: b_type_
sizeReturn = b_type_%size
end function sizeReturn
end module B
program main
use A
use B
implicit none
type(a_type) :: a_type_instance
type(b_type) :: b_type_instance
print *, a_type_instance%sizeReturn()
print *, b_type_instance%sizeReturn()
end program main
