[Bug fortran/34854] New: Valid USE statement is rejected

[fxcoudert at gcc dot gnu dot org]

I think both testcases below are valid, but gfortran rejects the
second one. They only differ in the order of USE statements.

$ cat test.f90
module common_init_conf
 integer, allocatable, dimension(:,:) :: Nmoltype_phase
end module common_init_conf

subroutine read_initial_config_nml()
 use common_init_conf, nmoltype_phase_com => nmoltype_phase
 use common_init_conf
 implicit none
 integer :: nmoltype_phase
 namelist /confNmoltypePhase/ nmoltype_phase
end subroutine read_initial_config_nml

$ gfortran -c test.f90 && echo OK
OK

$ cat test2.f90
module common_init_conf
 integer, allocatable, dimension(:,:) :: Nmoltype_phase
end module common_init_conf

subroutine read_initial_config_nml()
 use common_init_conf
 use common_init_conf, nmoltype_phase_com => nmoltype_phase
 implicit none
 integer :: nmoltype_phase
 namelist /confNmoltypePhase/ nmoltype_phase
end subroutine read_initial_config_nml

$ gfortran -c test2.f90
test2.f90:9.27:
