Description
for example here we can see that the location of the panic starts with a truncated absolute path:
error: this operation will panic at runtime
--> ices/121126.rs:2:22
|
2 | let _n = 1i64 >> [64][4_294_967_295];
| ^^^^^^^^^^^^^^^^^^^ index out of bounds: the length is 1 but the index is 4294967295

= note: `#[deny(unconditional_panic)]` on by default

error: the compiler unexpectedly panicked. this is a bug.
note: it seems that this compiler `1.79.0-nightly (4fd4797c2 2024-04-03)` is outdated, a newer nightly should have been released in the mean time

= note: please consider running `rustup update nightly` to update the nightly channel and check if this problem still persists
= note: if the problem still persists, we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md
note: please attach the file at `/home/gh-matthiaskrgr/glacier2_fz/rustc-ice-2024-04-04T21_03_46-3531616.txt` to your bug report
query stack during panic:

#1 [hir_attrs] getting HIR owner attributes in ``
#2 [entry_fn] looking up the entry function of a crate
#3 [analysis] running analysis passes on this crate
end of query stack
error: aborting due to 6 previous errors
Some errors have detailed explanations: E0405, E0412, E0425, E0562, E0666, E0670.
For more information about an error, try `rustc --explain E0405`.
the path of the panic starts inside the rustc repo at compiler/...
I'm wondering what causes the difference here.
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by comparing the two panic reports and the truncated source location for ices/121126.rs. Read the named compiler locations in compiler/rustc_target/src/abi/mod.rs and compiler/rustc_ast_lowering/src/lib.rs, then determine which code paths produce each panic location. Done means the inconsistent panic reporting behavior is reproduced, understood, and addressed with suitable validation.
