Current gfortran (trunk and head of 4.1 branch) segfaults when compiling the
following code:

module Precision
  integer, parameter :: dl = KIND(1.d0)
end module Precision

module ModelParams
use precision

type CAMBparams
  real(dl)::omegab,h0,tcmb,yhe
end type

type (CAMBparams) :: CP

contains

subroutine CAMBParams_Set(P)
  type(CAMBparams), intent(in) :: P
end subroutine CAMBParams_Set

end module ModelParams

module TimeSteps
use precision
use ModelParams

end module TimeSteps

module ThermoData
use TimeSteps
contains
subroutine inithermo(taumin,taumax)
  use precision
  use ModelParams
  real(dl) taumin,taumax

  call InitRECFAST(CP%omegab,CP%h0,CP%tcmb,CP%yhe)
end subroutine inithermo

end module ThermoData

This problem was not present a few days ago, and it is quite elusive. Even
adding or removing a few "!innocent" lines can change the error message,
e.g. to something like

 In file modules.F90:43

        use ModelParams
                      1
Error: The derived type 'p' at (1) is of type '', which has not been defined.

which makes no sense.
