This error seems to affect crates lock_api-0.4.10 and memoffset-0.9.0.  Logs are in xz, didn't fit under gz.

I haven't yet been able to find anything at all about this upstream...

Comment 3 Sam James archtester

It's got to be related to https://github.com/rust-lang/rust/issues/120701.

I don't see anything in recent lock_api or memoffset commits..

It looks like memoffset got removed too: https://github.com/rust-lang/rust/commit/28e60de4879786a02c215f83f8ba96f474bcbcaa, which is why 1.75.0 may be fine.

matoro do newer versions work?

In your log, there's also:
