Bug description

Compiling the current Camlp4 trunk (latest commit f2d62524324d903d5716d3be5c787d9dc5c43013 from github.com/ocaml/camlp4) with the current OCaml trunk (SVN revision 15568) gives:

/usr/local/ocaml-trunk/bin/ocamlc.opt -c -g -w a -I camlp4/import -warn-error A-3 -I camlp4/config -I camlp4/boot -o camlp4/boot/Camlp4.cmo camlp4/boot/Camlp4.ml

Fatal error: Parmatch.set_args
Fatal error: exception Misc.Fatal_error

I don't know whether this is a problem with OCaml or with camlp4 or an expected incompatibility between the two trunks, so I'm reporting the issue here as well as on the Camlp4 bug tracker.
