Thanks for this. It shows where the problem is: basically, ocamlbricks (which is a library used by marionnet) performs (via a function "f_") an Obj.magic on a format string, assuming it is internally a string, which is no longer true since ocaml 4.02.0 (4.02.3-3 has been uploaded to unstable on 2015-10-08). Marionnet has been broken since then.
I've checked in the latest trunk of ocamlbricks, and it is still broken:
http://bazaar.launchpad.net/~marionnet-drivers/ocamlbricks/trunk/view/head:/GETTEXT/gettext_builder.ml#L61
And I've checked in the latest trunk of marionnet, it still calls f_:
http://bazaar.launchpad.net/~marionnet-drivers/marionnet/trunk/view/head:/initialization.ml#L57
So the problem still exists upstream. I will submit a bug there. Cheers, -- Stéphane
