I am a bit fuzzy on exactly what's going on here, but this doesn't ring
a bell. So if you could create a reproducer, I can confirm whether this
is still present in the latest pre-release (and also hopefully clear up
the fuzziness).

This normally shouldn't be necessary so there is no explicit mechanism
for this. I think the first step should be to understand why there is a
segfault, not necessarily trying to force the base to be treated as
versioned when nothing about it has changed.
