A-LLVM Area: Code generation parts specific to LLVM. Both correctness bugs and optimization-related issues. C-bug Category: This is a bug. I-crash Issue: The compiler crashes (SIGSEGV, SIGABRT, etc). Use I-ICE instead when the compiler panics. P-high High priority regression-untriaged Untriaged performance or correctness regression. T-compiler Relevant to the compiler team, which will review and decide on the PR/issue.

Code

I tried these commands:

git clone https://github.com/bjorn3/rustc_codegen_cranelift cg_clif
cd cg_clif
git checkout b97201088788c11b66e711d1e9cfa480c947f3d3
./y.sh prepare
CARGO_BUILD_INCREMENTAL=false ./y.sh test --use-backend llvm --skip-test testsuite.no_sysroot --skip-test testsuite.base_sysroot

I expected to see this happen: Compiles

Instead, this happened: Rustc SIGSEGV's.

error: could not compile `ciborium` (lib)

This requires disabling incremental compilation as well as using a custom built sysroot. I'm not passing any weird arguments when building the sysroot and because of the --use-backend llvm everything is compiled using the regular LLVM backend.

This is causing cg_clif's CI to fail as it checks that it's test suite passes with LLVM: https://github.com/bjorn3/rustc_codegen_cranelift/actions/runs/6574776266/job/17861480553

A workaround is:

[profile.dev.package.proc_macro]
codegen-units = 1

A small reproduction is:

use serde::Serialize;

#[derive(Serialize)]
struct Internal {
}

It may be an alias related issue. I am not really sure. But I started trying to address it.
