rustc unexpectedly overflowed its stack! this is a bug

[Julianzs]

I get this whenever compiling with the following lines in my Cargo.toml:

[profile.release]
lto = true

If I remove these lines, compilation works fine. Otherwise, I see the below. I'm happy to provide more information if helpful.

error: rustc interrupted by SIGSEGV, printing backtrace

[Noratrieb]

Do you have a reproduction?

[Julianzs]

I can reproduce this on multiple machines, yes. Does that answer your question?

[Noratrieb]

No, I wasn't clear, I meant whether you can provide a reproduction for us.
But I also just noticed that you're using an old version of Rust, does this still reproduce with the latest nightly?

[Julianzs]

Here's how I reproduced:

1. Check out this repo: https://github.com/anza-xyz/agave/tree/v2.1.11
2. Add the following lines to the Cargo.ToML in the root directory

[profile.release]
lto = true
3. Run the build script in the repo (https://github.com/anza-xyz/agave/blob/v2.1.11/scripts/cargo-install-all.sh) which calls cargo build.

On each machine, this produces the same error. Note that for previous versions of this same repo (2.0.22), the build does not fail with an error.

I'm not sure how to use a newer rust version as I believe the build script selects on for me. I'll admit I'm somewhat new at this. :)

Does that help?

[Julianzs]

Hi @Noratrieb I see that another issue was linked here. Does that mean this is a known issue?
