Reword unstable fingerprints ICE to ask for reproduction When the unstable fingerprints error was added, Rust was on fire, and we needed a quick way for people to sort of understand what's going on, follow the tracking issue, and leave some information without overwhelming the issue tracker and focusing on getting their code working. This is what motivated the previous message. It called this a "known issue", provided help on how to fix it, and only secondarily asked for a bug report. This is no longer true. These days incremental compilation is fairly solid and these issues are supposed to be rare, we expect *none* of them to exist (but obviously know that's not true). As such, it's time to reword this message. Recently someone mentioned how they didn't bother reporting this issue because it said that it was a "known issue", and I only got awareness of their problem because they complained about all the rustc-ice files hanging around their directories (https://github.com/rust-lang/rust/issues/147825#issuecomment-3417297842). This is not at all what we want, we want reports from people, ideally with a reproduction. To get this, I reworded the error. It now explicitly asks for a reproduction (and explaining what that means) and no longer calls it a "known issue". It also does not link to the tracking issue anymore, because I don't think this tracking issue is useful. It should probably be closed. I still mention the workaround, but explicitly call it a "workaround". People should report a reproduction and only *then* use the workaround. |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
