Yes, I posted the link to the reproducing steps in the pull request.
Since MPL is now reverted, the steps change a little:
1. Checkout libs/mpl from my fork
https://github.com/lastique/mpl/tree/modularization. This is how MPL
looked before it was reverted. You can do it like this:
git remote add lastique git_at_[hidden]:Lastique/mpl.git
git fetch lastique
git checkout modularization
At this point you should see modularized MPL - there will be
2. rm -f bin* boost
3. cd tools/regression/build
4. b2 -q
5. Notice that this directory is missing: boost/mpl/aux_/preprocessed.
You will also notice that a lot of boost/ content is missing.
