Well, in a build without assertions enabled then yes it doesn't crash.
But if you do have asserts enabled in 16, it does crash.

The error would not occur on detach, but on attach, and it'd be intended
to prevent an inconsistent situation. I'm proposing that on older
branches we do what Tender proposed elsewhere, namely to cope with the
detach without crashing (and without leaving inconsistent catalog state,
such as bogus coninhcount values).
