ICE when compiling with -Zbuild-std and -Zno-profiler-runtime

[egkoppel]

Code

#![no_std]
#![no_main]

#[no_mangle]
extern "C" fn main() -> ! { loop {} }

#[panic_handler]
fn panic_handler(_: &core::panic::PanicInfo) -> ! { loop {} }

Compiling with cargo rustc -Zbuild-std=core --target x86_64-apple-darwin -- -C panic=abort is successful and produces a working executable. Adding -C instrument-coverage -Z no-profiler-runtime to the RUSTFLAGS environment variable produced the following compiler error. (Also tested with x86_64-unknown-linux-gnu and x86_64-unknown-none which produces the same results.)

rustc version: 1.78.0-nightly (2d24fe591 2024-03-09)
platform: x86_64-apple-darwin

query stack during panic:
#0 [optimized_mir] optimizing MIR for `intrinsics::vtable_size`
end of query stack

[egkoppel]

Building with nightly-2024-03-05 seems to work fine, but anything newer has an ICE

[durin42]

cargo-bisect-rustc points to 2eeff46

[durin42]

I suppose I should tag @oli-obk on this bug

[oli-obk]

Probably going to be fixed by #122037

[jieyouxu]

I tried it locally with

RUSTFLAGS="-C instrument-coverage -Z no-profiler-runtime" cargo +nightly rustc -Zbuild-std=core --target x86_64-apple-darwin -- -C panic=abort 

and it no longer ICEs. @egkoppel does it still crash for you on latest nightly?

[egkoppel]

I just tried it again with 1.79.0-nightly (4fd4797c2 2024-04-03) and it seems to still crash, although it seems unrelated to the original issue and instead to do with symbol mangling of f16 and f128 related functions.

Since that seems unrelated, would it make sense to close this issue as it seems to be resolved and open a new issue instead for the other problem?

Yes, please close this issue since it seems to be resolved, and open another one for the f16/f128 issue. Thanks!
