--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- The LTO minor saw a bump around Sep 10 last year already so the object files must be younger or LTO should complain. The specific assert that triggers isn't a sign of format divergence (it would be a very odd one to trigger) but instead there's an unexpected out-of-band tree object in the stream. Can you maybe reproduce the issue without re-using old objects? I'm not aware of any specific change where we forgot the bumping but there were a lot of changes and since we did already bump bumping again shouldn't cause any harm. Still I'd like to be sure we're not seeing a genuine streaming bug here.
