I believe DG internally replicates a multi-line error on each line
involved, so that the following markup is correct:

> module m

>       subroutine s1(i) ! { dg-error "Ambiguous interfaces" }

See for example gfortran.dg/dec_union_7.f90:

$ gfortran -fdec-structure dec_union_7.f90
...
dec_union_7.f90:24:23:

       integer(4) :: x = 1600 ! { dg-error "Conflicting initializers" }
                       1
dec_union_7.f90:29:20:

       integer :: e = 0 ! { dg-error "Conflicting initializers" }
                    2
Error: Conflicting initializers in union at (1) and (2)
