This worked fine with libc v0.2.164 - https://github.com/open-telemetry/opentelemetry-rust/actions/runs/12017744786/job/33500761123?pr=2339

Just to add - also tested with latest sysinfo v0.32.0, and still the same error.

Maybe it's due to rust-lang/libc@f4bbbc8

Published 0.32.1 version.

[workingjubilee]

yanking the broken libc version ASAP

[emostov]

Just in case it quickly helps anyone landing here, you can pin libc to the previous version

 cargo update -p [email protected] --precise 0.2.164`

[ultamatt]

FYI bumping into this myself right now. Thanks to everyone who's on the hunt to resolve this.

Adding my error from my pipeline in case it assists. Running on a macos-12 runner

libc 0.2.165 was yanked, 0.2.166 just released with a fix for this https://github.com/rust-lang/libc/releases/tag/0.2.166

[Noratrieb]

Thanks for taking swift action to fix that mistake in libc! And for everyone else here: please complain to libc next time instead of just silently patching around the bug :)
