Thanks.  I should have thought to do this testing myself.

This particular failure comes because the order of destruction of the
per-bfd and per-objfile objects changed.  I think it's better to avoid
this problem entirely.  I've got a patch to do this that I will send
soon.

After that's in, I'll rebase the registry series and test it with ASAN.
