Hello all,

I see the following Boost.Option regression test failures on develop branch:

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.
