Compiler deconstructing structure constructor

I used the numbers spat out by the compiler for my weekly lotto pick, but I didn't win anything.  Oh well.

MODULE m20150828
  IMPLICIT NONE

  TYPE :: ParentType
    CHARACTER(:), ALLOCATABLE :: string
  END TYPE ParentType

  TYPE, EXTENDS(ParentType) :: ExtensionType
  END TYPE ExtensionType

  TYPE :: OtherType
    CHARACTER(:), ALLOCATABLE :: other_string
  END TYPE OtherType
END MODULE m20150828

PROGRAM p
  USE m20150828
  IMPLICIT NONE
  TYPE(OtherType), ALLOCATABLE :: array(:)
  CLASS(ExtensionType), ALLOCATABLE :: object

  ALLOCATE(object)
  object%string = 'initiating compiler self-destruct sequence!'

  ALLOCATE(array(1))
  array(1) = OtherType(OTHER_STRING=object%string)
END PROGRAM p
