I'm getting an ICE and segmentation fault in the following code. I think it may
be related to Paul Thomas's observation about pointers to components of derived
type arrays. However, it does compile under these circumstances:
* when foo and bar are not in the module
* when the module contains foo or bar but not both
* when the types a and b have no reference to each other
* when ", only, a (or b)" is not used on the use statement
MODULE type_mod
TYPE a
INTEGER :: n(10)
END TYPE a
!
TYPE b
TYPE (a), POINTER :: m(:) => NULL ()
END TYPE b
END MODULE type_mod
MODULE seg_mod
CONTAINS
SUBROUTINE foo (x)
USE type_mod, ONLY : a ! fails
! USE type_mod ! works
IMPLICIT NONE
TYPE (a) :: x
!
RETURN
END SUBROUTINE foo
!
SUBROUTINE bar (x)
USE type_mod, ONLY : b ! fails
! USE type_mod ! works
IMPLICIT NONE
TYPE (b) :: x
!
RETURN
END SUBROUTINE bar
END MODULE seg_mod
gfc -c type_mod.f95 seg_mod.f95
seg_mod.f95:0: internal compiler error: Segmentation fault
