Description janus 2010-08-30 20:30:02 UTC

Reported by Andrew Benson at http://gcc.gnu.org/ml/fortran/2010-08/msg00462.html:


module Merger_Trees
  private
  public :: mergerTree

  type mergerTree
   contains
     procedure :: getNode => Tree_Node_Get
  end type mergerTree

contains

  function Tree_Node_Get(thisTree,nodeIndex) result(foundNode)
    implicit none
    class(mergerTree), intent(inout) :: thisTree
    integer,           intent(in)    :: nodeIndex
    integer,           pointer       :: foundNode

    return
  end function Tree_Node_Get

end module Merger_Trees


gives:


<During initialization>

Error: Pointer initialization target at (1) must have the SAVE attribute
