[Bug fortran/52729] New: Symbol has no implicit type in SELECT TYPE block


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52729

             Bug #: 52729
           Summary: Symbol has no implicit type in SELECT TYPE block
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: abenson@caltech.edu


The following fails to compile with the latest gfortran 4.8 (r185768):

module testMod

  type testType
  end type testType

contains

  subroutine testSub()
    implicit none
    procedure(double precision ), pointer :: r
    class    (testType         ), pointer :: testObject
    double precision                      :: testVal

    select type (testObject)
    class is (testType)
       testVal=testFunc()
       r => testFunc
    end select
    return
  end subroutine testSub

  double precision function testFunc()
    implicit none
    return
  end function testFunc

end module testMod

$ gfortran -v
Using built-in specs.

$ gfortran -c test.F90 -o test.o
test.F90:16.23:

       testVal=testFunc()
                       1
Error: Symbol 'testfunc' at (1) has no IMPLICIT type

Removing the "r => ...." line, removing the "select type", "class is" and "end 
select" lines or moving testFunc before testSub in the file all allow the code 
to compile successfully.
