Originally posted by @robojumper in #8868 (comment)

I'm hitting a similar error in a workspace of mine, although the problem is different in that a workspace dependency is not rebuilt when running cargo check and shows errors based on outdated versions of workspace crates, even though I have successfully ran cargo run --release often in the meantime. For reference, I'm running cargo check on https://github.com/robojumper/uc-analyzer/commit/a2c5c14b4b9d05f8a05bec5f24d9edb102b1a3f4 and I'm getting

error[E0004]: non-exhaustive patterns: `&DelegateCallExpr { .. }` not covered
    --> uc_ast_lowering\src\body.rs:1291:32
     |
1291 |         let (kind, ty) = match &expr.kind {
     |                                ^^^^^^^^^^ pattern `&DelegateCallExpr { .. }` not covered
     |
     = help: ensure that all possible cases are being handled, possibly by adding wildcards or more match arms
     = note: the matched value is of type `&uc_ast::ExprKind`

even though the variant had been removed in https://github.com/robojumper/uc-analyzer/commit/8f11b9adfe246aa3793b7ab92040c2f6a3eef51b, 14 hours/4 commits earlier. Changes to uc_ast_lowering\src\body.rs do not make the error go away.

This is despite cargo run --release working fine. I rarely run cargo check, most often just cargo run --release, and rust-analyzer invokes cargo clippy quite often.

I can't reproduce this from a fresh checkout, but I have a zipped copy of the project + target directory that I can use to reproduce this in a different folder.

@robojumper Can you share the ZIP file you have?

Can you reproduce it if you delete the target/debug/incremental directory?

Deleting the target/debug/incremental directory has no effect on this error.

I should've thought to add: This is on cargo 1.58.0-nightly (294967c53 2021-11-29), and I'm quite certain this has happened at least once before, when working on this project a few days earlier with the same nightly. Back then I ran cargo clean, which expectedly fixed it. That's why I took the zip snapshot and decided to report the issue.
