This has been an issue before (#88), but now it has reached rustc beta: https://github.com/ruffle-rs/ruffle/actions/runs/9462151873/job/26064482962?pr=16448

RUSTFLAGS="-C link-args=-znostart-stop-gc" does indeed work around this.

fix nightly build

In recent versions of the nightly / beta compilers, the use of linkme
causes linker errors. (dtolnay/linkme#94) This
is due to the new linker set as default in these versions.

Add linker flags to nightly builds to revert to the old linker
behaviour.

It seems to really be a dup of now-long-standing #49 (see that digit switch? what a coincidence!)

BTW, what was the platform in this case? (distro, libc, cc toolkit; with versions) I am wondering how to pinpoint the real culprit.

I have realised the main post had a ref to GHA running Ubuntu 22.04 which has clang in version 14 https://packages.ubuntu.com/jammy/clang and obviously runs glibc
