Also the omake issue: ocaml-omake/omake#71

[camlspotter]

This is a bug of OCamlPackage which does not work with parallel build. omake.0.10.1 builds things in parallel by default...

[camlspotter]

ppx_test.1.4.0 now uses its own fixed version of OCamlPackage, I guess it is now fixed.

@camlspotter are you fully positive this is fixed ? If that is the case then this can be closed.

[camlspotter]

Yes, please close it.
