Flycheck entirely broken for cg_clif

[bjorn3]

rust-analyzer version: rust-analyzer version: 0.3.1131-standalone (897a7ec 2022-07-17)

rustc version: rustc 1.64.0-nightly (263edd43c 2022-07-17)

relevant settings: rust-analyzer.linkedProject is set in .vscode/settings.json inside the cg_clif repo. It includes the main crate which I edited. No relevant settings at user level.

When introducing a deliberate non-syntax error I don't get any errors from flycheck. Syntax errors are reported though.

Does cargo check actually report any errors?

[bjorn3]

Gotcha

error[E0514]: found crate `cfg_if` compiled by an incompatible version of rustc

Looks like something got messed up when switching between nightly versions without cargo clean. cargo clean did the trick.

[lnicola]

Shouldn't we report that error? 😬
