Hi Wael,
Can you be more specific about which version of groff you upgraded
from and which one you upgraded to?
When I run your sample input on groff 1.22.4 (or earlier versions,
even 1.19.2), the two columns aren't aligned:
$ cat wael-test.ms
.mk
.DS L
Left-aligned side
.DE
.rt
.DS R
Right-aligned side
.DE
$ nroff -ms wael-test.ms | head
Right-aligned side
Left-aligned side
So it'd be helpful to know what version you upgraded from where these
two columns were aligned for you. But I do observe that in both those
older groffs, removing the .DE line does give the results you
reported, including the error:
$ fgrep -v .DE wael-test.ms | nroff -ms | head
:0: macro error: diversion open while ejecting page (recovering)
Left-aligned side Right-aligned side
Further, when I run it using the latest (1.23) groff, the two lines
aren't next to each other at all.
$ nroff -ms wael-test.ms | head
s.tmac:wael-test.ms:4: error: must be in top-level environment, not
'nf', when first page is started
Left-aligned side
Right-aligned side
So I'm unable to reproduce your results, unless you upgraded from a
version even older than 1.19.2, to version 1.22.4 or something else
before 1.23.
