dune runtest fails on OCaml 4.12.0 #3766
Description
I ran opam-health-check on 4.12 overnight and I'm seeing lots of failures on OCaml 4.12.0 that all seem to be related to dune:
#=== ERROR while compiling re.1.9.0 ===========================================#
# context 2.1.0~beta2 | linux/x86_64 | ocaml-variants.4.12.0+trunk | file:///home/opam/opam-repository

### output ###

# ^^^^^^^^^

They all seem to fail when dune runtest or dune build @runtest is called and only appears on 4.12.0.
#3576 and ocaml/opam-repository#16983 seem to be related issues (cc @dra27)
Reproduction
- Install ocaml 4.12.0+trunk
- call
opam install -t re.1.9.0
