…-darwin I'm not sure if this is suitable for upstream, so I'd rather Apple address it in the next release.

Is this something we could avoid on the Rust side instead? e.g. don't add that attribute in the first place? It would be a hack either way, but I think lower maintenance overhead if we change "our" code. |
No :\ |

As per rust-lang/rust#140686 (comment) , Apple is not planning a fix. |
|
I know that Apple isn't planning to fix it, but maybe we should fix it anyhow? |
I can't be sure if this workaround will reliably support for the next five years (or longer), as I haven't debugged ld64 to find the root cause. I'm not sure if we should be supporting an end-of-life tool. Free to mention this issue at the compiler meetings. I can maintain this patch, but I don't know about the long-term direction. Perhaps someone could take over the maintenance of ld64, but who would review their changes? |

Fair enough |
@madsmtm FYI, this has been sent to upstream via llvm#142304. (You've probably already seen it.) |

Yeah, I did, thanks a lot! |
This reverts c458123 which reverted the upgrade to rust-1.86.0. The upgrade to rust-1.86.0 in d1dc4c2 was initially reverted since it caused the `//rs/pocket_ic_server:...` and `//packages/pocket-ic:...` tests to fail on x86_64-apple-darwin. We have now debugged this failure and it turns out this is due to a bug in the apple linker that causes bad code to be generated for the `hyper` HTTP client crate used in both the pocket-ic library and server. (Full context [here](rust-lang/rust#140686 (comment))). LLVM has a [workaround](rust-lang/llvm-project#181) that they merged and rustc will integrate it soon. Until then, it appears that the bug is only triggered when building with the default `opt-level=2`. Until we’ve upgraded to the newest rustc (for which we’ll need to wait for a new rules_rust version) we will build the `hyper` crate with `opt-level=0`(I tried `opt-level=1` but that results in the same failure). This rust upgrade should also fix the non-reproducibility of the `archive_canister_u256` and related canisters. --------- Co-authored-by: IDX GitHub Automation <> Co-authored-by: Martin Raszyk <martin.raszyk@dfinity.org>
