I can gather more details on this failure if needed.

Thanks.

Further details: noticed that this problem is after installing async (113.33.00, looks like):

It is an incompatibility with Jane Street Core/Async libraries in OPAM and the dev version. Is it possible to use Janestreet's bleeding-edge version of their libs:

opam repo add janestreet-bleeding https://ocaml.janestreet.com/opam-repository

I'm developing against those libraries since they will release very soon. Thanks.

Ah; right; it makes sense; thanks. Closing it.
