New internal error on nightly-2022-11-10

[nik9000]

Summary

Sorry I don't have a minimal example! But I was able to bisect the problem to the release on nightly-2022-11-10. I don't know rust at all so I'm sure I'm writing some non-canonical thing patterns. I'd be happy to try and make a reproduction if there was some way to get a hint of where to start. I looked at the Bug Minimization Patterns and didn't have a whole lot of luck on my side.

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

[nik9000]

rustc 1.67.0-nightly (42325c525 2022-11-11)

Looks like the problem first appeared in 2022-11-10.

[Chralt98]

I am experiencing the same with nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.67.0-nightly (6284998a2 2022-11-12).

Seems to be solved with nightly-aarch64-apple-darwin unchanged - rustc 1.67.0-nightly (e631891f7 2022-11-13). Although it's another machine (linux to macos), but I had the same error on MacOS before the update to e631891f7.

[xFrednet]

Without a minimum reproducible example this is hard to investigate. The comment from @Chralt98 seems to indicate that this was fixed. Otherwise, it was suggested that this is a duplicate of #9846

Therefore, I'll close this for now. If you still have this issue, please create a new issue. You can also link a repo with the bug
