--- Comment #56 from Alexander von Gluck <kallisti5 at unixzen dot com> --- Canadian builds are pretty important in GCC. clang doesn't really need Canadian builds since they support all targets out of the box on every platform, but we don't have that luxury with gcc. With that said, the proposed patch solved the issue for us and we applied it to our toolchains here: https://github.com/haikuports/haikuports.cross/blob/master/sys-devel/gcc_bootstrap/patches/gcc-11.2.0_2021_07_28.patchset
