You don't get one with groff 1.18 -- \n[.V] for devps output is *very*
small (1/72000 inch). Anyway, it increases the vertical position
counter which probably triggers some trap (I haven't checked the code)

movement.

You haven't tried hard enough:
groff -ww mini.t > mini.ps
gives
mini.t: warning: vertical spacing must be greater than 0

I've tested your file, and I can confirm your problem. Doing the
replacement suggested in my first answer fixes it, giving identical
results with both 1.18 and 1.19.
