ICE compiler/rustc_metadata/src/rmeta/def_path_hash_map.rs:23:85 on stable

Open ijackson opened this issue 3 years ago • 1 comments

Code

I don't have a minimal repro. Moving target aside makes the bug go away. Putting the "busted" target back makes it reappear, so this looks like an incremental compilation bug. The target directory in question is 42Gb.

I was running cargo clippy. Switching to cargo check makes the bug go away.

The error message is:

thread 'rustc' panicked at 'called `Option::unwrap()` on a `None` value', compiler/rustc_metadata/src/rmeta/def_path_hash_map.rs:23:85

I think this is probably #100521 but here it's happening on stable.

For my reference: this occurs with arti#8b7a07d7ea36128b9c397cd50d0092c14cda921e. I have saved target as /volatile/rustcargo/Rustup/Arti/Bug-ICE-2022-10-17-target. My build rune is in the stack trace below.

@rustbot modify labels +A-incr-comp

This is probably still happening on stable because the fix hasn't been released to stable yet I think

Noratrieb avatar Oct 17 '22 20:10 Noratrieb

The fix in question has landed and I am going to benignly assume that this issue is now resolved and redundant. And if I am wrong, sketchy incremental compilation errors like this will resurface soon enough.
