libffi-3.4 has no API changes but has a trampoline change that is known to expose bugs in apps: - ghc has too optimistic assumption about executable memory: https://gitlab.haskell.org/ghc/ghc/-/issues/20051 - gobject-introspection uses incorrect object as a closure: https://gitlab.gnome.org/GNOME/gobject-introspection/-/merge_requests/283 Both are currently mitigated by disabling USE=-exec-static-trampoline default. But more might lurk in the shadows. This is a tracker bug. No talking here please. Let's gather typical failures and examples of fixes at: https://wiki.gentoo.org/wiki/Project:Toolchain#libffi-3.4

Feel free to test this flag, but be aware of possible breakage. Let us know of any bugs!
