[Bug fortran/16861] segfault with doubly used module

[paul dot richard dot thomas at cea dot fr]

The 11th November still gives this behaviour.  However, if the USE FOO is 
raised to the module level, all is well.  For example, this slightly expanded 
version compiles and runs fine.

module FOO
  integer :: I=2
end module FOO

module BAR
  use FOO
contains
  subroutine BAZ(J)
    integer, dimension(I) :: J
    print * ,"BAZ: size(j) =", size(J)
  end subroutine BAZ
end module BAR

subroutine QUUS()
  use FOO
  use BAR
end subroutine QUUS

program test_mod
  use FOO
  USE BAR
  integer, dimension(I)    ::   j 
  I=3  
  call BAZ(j)
  call QUUS(2)
  print * ,"MAIN: size(j) =", size(J)
end program test_mod
