note: 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: rustc 1.83.0 (90b35a623 2024-11-26) running on x86_64-unknown-linux-gnu

note: compiler flags: -C opt-level=3

query stack during panic:
#0 [optimized_mir] optimizing MIR for `return_str::{closure#0}`
#1 [layout_of] computing layout of `{async fn body of return_str()}`
end of query stack
error: aborting due to 18 previous errors

Some errors have detailed explanations: E0107, E0277, E0308, E0412, E0600.
For more information about an error, try `rustc --explain E0107`.

Anything else?

Note that the bug can only be reproduced by rustc -C opt-level=3 --edition=2021 1.rs .
If we remove -C opt-level=3, the ICE disappears.

    @wangbo15 are these ICEs fuzzer-generated?

    👨 🦋 Is this minimized?

    @jieyouxu Yes, I apologize for trying to minimize it, but it is still oversized.

    Please refer to fuzzing guidelines, in particular please disclose that the ICE is generated through fuzzing.

    Also, -Copt-level=3 is not needed, -Copt-level=1 is sufficient to ICE stable rustc (1.83.0). Please try the minimum opt-level as well since this is fuzzed.
