Rejects valid: dummy argument names must be the same

I’m trying to compile OpenMC (GitHub - openmc-dev/openmc: OpenMC Monte Carlo Code) with the PGI 16.10 community edition compiler and I’m running into the following error:

PGF90-S-0155-Dummy argument names must be the same as those in parent's interface for type bound procedure get_next_bin_energyfunction (/home/romano/openmc/src/tally_filter.F90: 1649)

The relevant function has dummy arguments declared as follows (see openmc/tally_filter.F90 at 7f41ab2babe4742c41f96f0459dde1dd6d4df288 · openmc-dev/openmc · GitHub):

  subroutine get_next_bin_energyfunction(this, p, estimator, current_bin, &
       next_bin, weight)
    class(EnergyFunctionFilter), intent(in)  :: this
    type(Particle),              intent(in)  :: p
    integer,                     intent(in)  :: estimator
    integer, value,              intent(in)  :: current_bin
    integer,                     intent(out) :: next_bin
    real(8),                     intent(out) :: weight

The abstract class that EnergyFunctionFilter extends has a deferred type-bound procedure with its interface defined as follows (see openmc/tally_filter_header.F90 at 7f41ab2babe4742c41f96f0459dde1dd6d4df288 · openmc-dev/openmc · GitHub):

  abstract interface
    subroutine get_next_bin_(this, p, estimator, current_bin, next_bin, weight)
      import TallyFilter
      import Particle
      class(TallyFilter), intent(in)  :: this
      type(Particle),     intent(in)  :: p
      integer,            intent(in)  :: estimator
      integer, value,     intent(in)  :: current_bin
      integer,            intent(out) :: next_bin
      real(8),            intent(out) :: weight
    end subroutine get_next_bin_

As you can see, all the dummy argument names seem to match, so I’m not sure why the compiler is rejecting it.
