release 0.13.2 came out 12 hours ago. Looks related. https://github.com/eqrion/cbindgen/commit/17d7aad7d07dce8aa665aedbc75c39953afe1600

You think this provides a fix or caused the break? It seems unlikely to have caused the break since the travis logs show the one we ask for in our Cargo.lock - 0.8.7 - is used.

I suspected that it caused the break but haven’t yet looked closely if actually true. My suspicion came from this release being 12 hours old, which corresponds to when Benjy first flagged the issue.
