I see what you're saying about the metadata being incorrect; I feel like I've seen it before, but can't pin it down. For the record, all the builds where we saw this assertion were thin/full LTO.

I've kicked off a reduction of a large reproducer that I have to hand; I'm not immensely confident that it'll complete in a reasonable timescale (i.e.: days) as it's a large project being reduced. If any of the other reporters have anything smaller they can reduce, that'd assist significantly.
