Hi Lorenzo, Issue 1 is a bug in the implementation of Optional that I introduced a couple of days ago. This has been now reverted, but we will still see the error reports for the next couple of days in the test matrix. Issue 2 seems to be the communication problem between the compiler and the standard library, but I do not know anything specific. Regards, &rzej; 2017-11-05 2:02 GMT+01:00 Lorenzo Caminiti via Boost :

Hello all,

I see the following Boost.Option regression test failures on develop branch: http://www.boost.org/development/tests/develop/developer/optional.html

The first error only shows on develop, the second error shows up on both develop and master regression tests.

Do you know what the issue is on this toolset/platform?

I am asking because Boost.Contract uses Boost.Option so it is showing the same failures.

Thank you. --Lorenzo

It seems like there are a lot of failures in the teeks99-02-dc5-1z-lc-Docker-64on64 (clang 5, -std=c++1z -stdlib=libc++) that aren't in the teeks99-02-dc5-1z-Docker-64on64 (clang 5, -std=c++1z)...and that is the only config that uses libc++, so I'm guessing it is an issue with the libc++ install on that docker image. I'll look at it when I get a chance...if anyone else has experience setting up libc++ on ubuntu I'd be happy to take a pull request for the docker image or command arguments: https://github.com/teeks99/boost-cpp-docker/tree/master/clang-5 https://github.com/teeks99/boost-build/tree/master/Regression Tom
