rust (original) (raw)

Code

I'm too new to rust to know what part of this project is causing the compiler to crash, so I made a branch for it and removed the dependency on fltk. https://github.com/battjt/cb-test/blob/rustc_bug/src/main.rs

Same failure in nightly, beta, and stable

note: the compiler unexpectedly panicked. this is a bug.

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 1.55.0-beta.9 (27e88d367 2021-08-28) running on x86_64-unknown-linux-gnu

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -C incremental --crate-type bin

note: some of the compiler flags provided by cargo are hidden
