Bug #: 55855
Summary: incorrect warning with type-bound procedure pointer
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: abenso...@gmail.com
The following:
module eventMod
type, public :: event
private
procedure(eventTask ), pointer, public :: task
end type event
abstract interface
logical function eventTask(self)
import event
class(event), intent(in) :: self
end function eventTask
end interface
end module eventMod
program test
use eventMod
implicit none
logical :: r
type(event), pointer :: myEvent
allocate(myEvent)
r=myEvent%task()
end program test
causes the following warning when compiled (with gfortran 4.8.0):
$ gfortran -v
Using built-in specs.

Warning: POINTER valued function appears on right-hand side of assignment at
(1)
As far as I can tell, the code runs correctly despite this warning.
the warning is spurious as the "task" function returns a logical, not a
pointer.
