@bors r+ -- I think I recently saw this fail on Travis, too, but the overall build didn't fail. Did you see the doctests failing locally and stopping the build in the entirety?

@Mark-Simulacrum I just find it annoying that the failing test appear before make tidy 😄

The strange thing is that even if the test failed, the return code is still 0 (success), so while it should stop the build, it doesn't. Also, I expect the content should be collapsed between check-bootstrap in Travis, but it is still appearing 😕. I may push a new commit to fix that.

@Mark-Simulacrum OK now the check-bootstrap should properly detect if all tests are successful, and stop the CI on failure. Also content is now properly collapsed in Travis.

Thanks!
