A heads-up that if you build this release with the latest stable version of GCC, 15.2, it'll crash inside the layout engine: https://bugzilla.mozilla.org/show_bug.cgi?id=1990430

Crashes with GCC 15.2

gcc bugs (or any other compiler or artifact-generating toolchain bug for that matter) that do not cause an immediate ICE and crash the build are extremely annoying (and sometimes quite dangerous), but hunting down everything that was miss-compiled in the distro and triggering a new binary upload while somehow ensuring the auto-builder does not have the broken compiler/toolchain installed is an annoyance on its own class.

Debian has "Built-Using", and I assume other distros also have their own build-chain-tracking systems, but still...
