I find it both amazing and scary that Boost.Build has an interactive
debugger.
In any case, if you use the docker container in the pull request in
boostorg/boost
you would probably be able to reproduce this because it pulls in
dependencies
of many of the repositories.  For example the docker container is using
Python 3.6.

(might I suggest aliasing "bt" for "backtrace" in the Boost.Build debugger?)

```
(b2db) backtrace
