Travis started to fail

[qnighy]

Currently #44 (build #929) and #45 (build #930) fail (for seemingly the same reasons). As #44 is a trivial change, they must be spurious errors.

I couldn't figure out the exact cause. Seems to be related to core_kernel.

I get the same error message as https://travis-ci.org/gfngfn/SATySFi/builds/348081919 while packaging SATySFi for Nix; I would love to know how to fix it.

I'm at 042a8aa and I'm getting this error since 26aa766 so the error might be originating somewhere else...

@mt-caret #47 might help you.

I tried to bisect dune (formerly jbuilder) between 1.0+beta17 and 1.0+beta18 with the following test script:

opam reinstall -y jbuilder
opam reinstall -y core_kernel

Bisect reported ocaml/dune@9e4cc84 as the first bad commit.

I can confirm, #47 indeed fixes the error. Thank you!

An upstream bug, then?

[qnighy]

Probably. I'm investigating further.

The bisect procedure above was wrong; now I pinned jbuilder and satysfi to local repos and bisected on jbuilder with the following script:

opam reinstall -y jbuilder
opam reinstall -y core_kernel
opam reinstall -y satysfi

Bisect reported ocaml/dune@b383828 as the first bad commit.

[mt-caret]

There's a PR that might be addressing the issue: ocaml/dune#567

[qnighy]

Confirmed locally that the current master (ocaml/dune@e4aac2d) does not cause the Core_kernel__ problem. I think it is good to pin to 1.0+beta17 until 1.0+beta19 is released.
