Reduced test case for this error:

  implicit none

  type :: process_variant_def_t
  end type

  type :: process_component_def_t
     class(process_variant_def_t), allocatable :: variant_def
  end type

  type(process_component_def_t), dimension(1:2) :: initial
  associate (template => initial(1)%variant_def)
  end associate

end


The error only occurs with the patch, but not with a clean trunk.
