~~Only can provide an unminified repro right now, located in this repo (branch rustc-bug-repro)~~

~~If you check out the previous commit the build will go through without any compiler errors or rustc panics:~~

PS> git branch
  master
* rustc-bug-repro
PS> git checkout HEAD^ 
Note: switching to 'HEAD^'.
[...]
HEAD is now at b1f9ba6 split up expr into col names and literals
PS> cargo build
   Compiling sqlite-starter-rust v0.1.0 (C:\DEV\build-your-own-sqlite)
    Finished dev [unoptimized + debuginfo] target(s) in 0.99s

~~So it must be something that happend in this commit, but I can't say what exactly yet.~~

I don't know what I did, but I can't reproduce it anymore. I started deleting and rebuilding until rustc didn't panice anymore. And now the unchanged repro can be built successfully too.

I guess the bug originated in the files rustc creates during builds for chaching or whatever and the repro wouldn't have worked on other machines anyway.

95th · 2021-12-22T15:01:14Z

I was about to raise the same issue. Seems to be an issue with incremental build. cargo clean and cargo build resolves it and I can't replicate anymore.

This should be fixed on the latest nightly.

95th · 2021-12-22T15:04:41Z

Since I can't replicate it anymore, I can't verify it.

prismatic-obloquy · 2021-12-22T16:55:43Z

Just hit this issue on stable with cargo check. Switching to (old) nightly leaves it there, so it's not going away just from switching versions. Updating to latest nightly fixes it and makes stable work again.

HTGAzureX1212 · 2021-12-23T04:39:33Z

This should be fixed on the latest nightly.

I have ran into a similar issue, but that also seems to be related to incremental compilation and is on latest nightly: #92221.

@95th I don't think that's the same ICE. Yours fails on compiler/rustc_query_impl/src/on_disk_cache.rs:500, while the one in this issue fails on compiler\rustc_hir\src\definitions.rs:452

See #92163

Oh you're right. I added my comment over there. Thanks
