We do not support multiple OCaml versions in the archive. As long
as that holds true, Unison <2.48 won't work with OCaml >=4.02.3.
For now, we've requested the removal of Unison 2.40 and 2.32 from
Stretch and we are looking for a solution to make 2.48 also work
in stable.

Thanks Mehdi,
I was able to install the packages from packages.debian.org here:

https://packages.debian.org/jessie/amd64/unison2.32.52/download
https://packages.debian.org/jessie/amd64/unison2.32.52-gtk/download

Then I installed them using dpkg -i and used:

apt-mark hold unison2.32.52
apt-mark hold unison2.32.52-gtk

...to hold those versions so they wouldn't be overwritten by the next apt
upgrade.

It now seems to work fine. Is there any reason the Jessie versions couldn't
be retained in Stretch instead of the broken unison2.32.52 version?

Unfortunately, there is no plan to downgrade OCaml's version in Stretch.
If you need a working Unison setup across multiple systems based on different
versions, you may copy needed Unison binary around, for now.

Is it at all feasible to downgrade the installed version of ocaml 4.01.x on
Stretch? I am reliant on Unison 2.32 (due to that being the most recent
version available for another device I use).

I'm only seeing the 4.02 version available in the repos.

$ apt-cache madison ocaml
 ocaml |   4.02.3-5 | http://ftp.nz.debian.org/debian stretch/main

The cause seems to be the recent 2.40.102-3+b1 rebuild.
2.40.102-3 doesn't have any problem.
