Comment 21 for bug 1568459

Just as a note on recompiling, I have tried to build a statically-linked binary on Ubuntu 19.10 (with OCaml 4.05.0) and run it on 20.04; it yields the same errors as the dynamically-linked 19.10 binary when run on 20.04:

Unison failed: Uncaught exception Failure("input_value: ill-formed message")

Perhaps someone more experienced with OCaml can add some insight.

I have added this information to the upstream bug report at <https://github.com/bcpierce00/unison/issues/334>. We may need to open a new bug, though, since this doesn't appear to be a packaging issue.
