I'm also seeing this on x86_64 with the recent nightlies: https://github.com/LiveSplit/livesplit-core/actions/runs/5980989859/job/16228118339#step:7:110 Update 1: It seems like in both cases it's related to cross. The original PR mentions problems with old Update 2: cross runs |

Centos 7 used by i686-dist builder seems to use Binutils 2.27, dist-armv7 uses Binutils 2.32 and dist-various1 (so thumbv6m-none-eabi) uses Binutils 2.38.

hashbrown ci uses cross 0.2.5, which is the latest stable release for cross. To fix this issue with cross specifically, one can set the image used by cross to be a newer version, cross 0.2.5 images use ubuntu 16.04, we can change that with the env vars or config (see comment)

The diagnostic looks similar to a binutils 2.41 change I made to fix https://sourceware.org/bugzilla/show_bug.cgi?id=24784 There is incompatibility between |
This reverts commit 4410868, reversing changes made to 249595b. This causes linker failures with the binutils version used by cross (rust-lang#115239), as well as miscompilations when using the mold linker.

Ran into this in github CI today as well (e.g. https://github.com/VorpalBlade/ini-merge/actions/runs/5990039532/job/16246920034). Works fine locally on Arch though when I try to recreate it. EDIT: Managed to reproduce it locally. I was mixing up -gnu and -musl targets, my bad. |

Posted a revert at #115267. |
This is really not a great solution for projects that build binaries for releases though (like I do). To target an old enough glibc to work on all systems (e.g. CentOS/RHEL, stable Debian, etc) you need to build on a fairly old distro. And then you also get older ld etc as well. It would be great if you could tell rust & gcc (for native dependencies) to target an older glibc than the system one, that would solve a lot of issues. |

In GCC/Clang, #106511 is to use modern GCC/Clang style I think I should keep arguing for #106380 |

I apologize to everyone, forgot about this issue. I can state that this issue is closed and no longer relevant. @Emilgardis' suggestion (as a workaround) and @nikic's pull request fixed the issue. |
