Unexpected compiler panic after changing struct's name

[aleksanderkrauze]

What happened

After I renamed a struct and tried to build my project compiler panicked with following message. However after doing a clean build everything was successful. I don't know how to extract code that is a cause for this panic, so here is my repo at the point of failure. Specifically the change I made was in file src/statusbar.rs. I also have a copy of target directory that fails to build. I won't attach it here because after compression it is 268M in size, but if is will be helpful I can share it in any way you wish.

If there is some additional information I can provide please let me know, I'll be happy to help. This is my first bug report of this kind, so I'm kinda guessing what should I include in it. Please also forgive me for butchering grammar since I am not a native-speaker.

This should be fixed on the latest Nightly

As this is from version 1.57, I am closing as a likely duplicate of one of these issues:

• thread 'rustc' panicked at 'called Option::unwrap() on a None value', /rustc/<snip>/compiler/rustc_hir/src/definitions.rs:452:14 #91696
• Trait selection provisional cache incorrectly handles DepNodes, leading to ICE #92987

Several fixes were put in to place to resolve this, see the PRs:

• Don't perform any new queries while reading a query result on disk #91919
• Fully serialize AdtDef #91924
• Properly track DepNodes in trait evaluation provisional cache #93064
