Yes. You should see a line that says:
- cxx11_smart_ptr : no (cached)
to indicate that it's using a previously stored value.

You can work around this with:
b2 -a --reconfigure
Ideally -a or --clean would be sufficient.
Unfortunately, the implementation saves the
result in two different ways, and both of
them need to be cleared.
