Yeah, it's a known thing. Before the rust changes firefox ebuild forced non-bin rust dep on musl, and maybe that needs to be put back for now. Although the real fix was related to something else, but I don't remember whether it was a rust thing, eclass thing or ebuild thing. Need to dig the discussion we had with sam a while ago in #gentoo-mozilla
bug 938847
Hi all, I have a *very* similar issue but with the following differences: - plain old glibc system (no musl) - thunderbird (not firefox) - uniffi_bindgen crate (not proc-macro2) But the segfault and outcome is the same. I had to p.mask 1.84.0 down to 1.83.0 to get a successful build. I opened a different bug (#948059) but I thought the issues were close enough (namely rust-bin) that I should mention it here too. Cheers.
