Hello I'm trying to compile lwt using ocaml 3.12.1 with the memprof patch [1] but I'm having problems compiling the Lwt_stream module, which uses objects. The error I get is exception Assert_failure("bytecomp/typeopt.ml", 323, 20) It seems that the patch needs to be modified to support object-oriented code [2] but I couldn't find anywhere which specific changes need to be made. Does anyone know what those are? Thanks, Andre [1]http://bozman.cagdas.free.fr/documents/ocamlmemprof-3.12.1.patch [2]https://groups.google.com/forum/#!msg/fa.caml/Lxuz6_-7HQ0/HSoqYFOw7QkJ
