When linking a library statically (stdc++) with a library crate, we need to add this:
However, if specified like this, the unit tests work fine, but the doc-tests fail due to being unable to locate many-many symbols from the stdc++ within the crate library.
It can be fixed by linking the whole archive:
But this seems to be a little redundant.
The question is if this is intended. If not, I wonder how one is assumed to be correctly linking then to avoid the problem for the doc-tests?
