Does not compile with OCaml 4.09.0 about camomile

[kousu]

I'm having problems too, but with a different error on OpenBSD. OpenBSD 6.6 has OCaml 4.09 in packages right now (https://openports.se/lang/ocaml) and

$ opam install camomile
The following actions will be performed:
  - install camomile 1.0.2

Does not compile with ocaml-4.12:

dune build @install

Error (alert deprecated): module Stdlib.Pervasives
Use Stdlib instead.

If you need to stay compatible with OCaml < 4.07, you can use the 
stdlib-shims library: https://github.com/ocaml/stdlib-shims

Fatal error: exception Stack overflow

I resolved this error (camomile 1.0.2, OpenBSD 7.0, OCaml 4.13.1) by increasing ulimits:

$ ulimit -n "$(ulimit -H -n)" -l "$(ulimit -H -l)" -s "$(ulimit -H -s)"

The adjustment to -n was probably not necessary.

Thank you @mndrix :)
