Confirmed for gfortran 4.3.4, 4.4.1, and trunk. The code compiles with gfortran
4.2.4, thus this is a regression. Reduced test:
module testmod
integer, parameter :: r8 = selected_real_kind(12)
type VARIABLES_MAILLE
real(r8), dimension(5) :: cell_var
end type VARIABLES_MAILLE
type (VARIABLES_MAILLE), pointer, dimension(:) :: Hydro_vars
real(r8), pointer, dimension(:) :: Ro
common/arrays/Ro
end module testmod
subroutine TF_AD_SPLITTING_DRIVER_PLANE
use testmod
implicit none
Ro => Hydro_vars(1:2)%cell_var(1)
end subroutine TF_AD_SPLITTING_DRIVER_PLANE
end
Note that if I comment the line " common/arrays/Ro" I get the following link
error:
Undefined symbols:
