Unexpected test failure in cohttp-lwt-unix

[mseri]

It may be nothing, I have only seen it in https://opam.ci.ocaml.org/github/ocaml/opam-repository/commit/99f42f52562e1e7c102071b42b1eeb5b98c611a2/variant/compilers,4.11,ocamlnet.4.1.8,revdeps,cohttp-lwt-unix.2.5.5

I think we should have a look when we have a moment

restarted that test to check if it's transient or not

Thanks, in any case this is not happening in a part of the codebase that was touched for 2.5.5. I am quite surprised that it appeared compiling cohttp-lwt-unix as a revdep of ocamlnet tbh

Indeed, it is gone.
