I can confirm this with latest master.

In general, framework is the preferred mechanism (should we disable this?) but in any case it shouldn't have this failure mode.

So with https://github.com/mono/Embeddinator-4000/pull/627 we're at least warning that this is unsupported and pointing people to use frameworks.

I'm not going to close this, since dylibs are broken, but it's much lower priority.
