Type bound generics and dotted strings

[IanH]

The following gives acompletly whackedspurious error message that indicates that "operator resolution" for a a user defined operator applied to a component of a derived type is being carried out based on the name of a dummy argument ... in a different procedure .... in a different module.

[fortran]

MODULE A
  IMPLICIT NONE
  PRIVATE
 
  TYPE, PUBLIC :: TypeA
  CONTAINS
    PROCEDURE :: is_op
    GENERIC :: OPERATOR(.is.) => is_op
  END TYPE TypeA
CONTAINS
  PURE FUNCTION is_op(str, idx) RESULT(mvconc)
    CLASS(TypeA), INTENT(IN) :: str
    INTEGER, INTENT(IN) :: idx    
    REAL :: mvconc
    mvconc = 0.0
  END FUNCTION is_op
END MODULE A

MODULE B
  IMPLICIT NONE
  PRIVATE
  PUBLIC :: irrelevant_proc
 
  TYPE, PUBLIC :: TypeB
  END TYPE TypeB
CONTAINS  
  ! Note dummy argument name.
  SUBROUTINE irrelevant_proc(My)    
    TYPE(TypeB), INTENT(IN) :: My
  END SUBROUTINE irrelevant_proc
END MODULE B

MODULE C
  USE A
  IMPLICIT NONE
  PRIVATE
  INTEGER, PARAMETER, PUBLIC :: rising =  1
 
  TYPE, PUBLIC :: TypeC
    TYPE(TypeA) :: exasperation
  END TYPE TypeC
CONTAINS
  SUBROUTINE proc(My)
    TYPE(TypeC), INTENT(INOUT) :: My
    PRINT *, My % exasperation .is. rising
  END SUBROUTINE proc
    
  SUBROUTINE another_proc
    USE B, ONLY: irrelevant_proc
  END SUBROUTINE another_proc
END MODULE C

Hello Ian,

A fix has been found for this issue. We are currently planning to include it the next major release which is scheduled for later this year.

This bug was fixed in the recent Composer XE 2013 SP1 release, released in early September ( version 14.0 of the compiler )
