The gift that keeps on giving. The fix I mentioned previously is now now tagged for rust-1.84.1. If you apply https://github.com/rust-lang/rust/commit/1dc106121b62562ead6e7d612fa136dc4b35cd5d.patch again on =dev-lang/rust-1.84.0, recompile rust with it (make sure it's applied) and try again, is it working?
Actually looks like 1.84.1 is out, maybe it's better to wait until that is packaged in Gentoo.

Upstream rust has managed to reproduced the crash in `rustc`, by compiling a version of the 'mls-platform-api' thirdparty library. https://github.com/rust-lang/rust/issues/138198 Upstream rust also determined that newer versions of 'mls-platform-api' appear to have already created a workaround to mitigate the original SIGABORT affecting <dev-lang/rust-1.84.0: https://github.com/awslabs/mls-rs/pull/231 Upstream rust verified just now that the workaround in the latest 'mls-platform-api' appears to prevent the same SIGABORT in `rustc` even after upstream rust's previous attempted fix in >=dev-lang/rust-1.84.0, because reverting the workaround in 'mls-platform-api' reintroduces the SIGABORT when compiling the third party library with the latest rustc.
Created attachment 920383 [details, diff] workaround.patch Applying the same workaround to 'mls-platform-api' folder, in `/etc/portage/patches/www-client/firefox/` appears to workaround the same crash on Gentoo, allowing the build to proceed. See workaround.patch **Note for novice users** This is not a fix for rust itself, but is enough to tiptoe around the issue while upstream rust is working on the real fix.
(In reply to Yuri Sevatz from comment #14) Thanks a lot for reporting this and finding a smaller reproducer!
just a quick confirmation: recently supplied patch fixes the issue: www-client/firefox-136.0 built successfully with dev-lang/rust-1.85.0-r1
juippis: could you add that in for now?
