--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- Note the message is from our package build process scanning for severe warnings and failing package build because of that. Thus there is a "no return in non-void function" warning generated by GCC during the build of libsanitizer, in the particular case on aarch64-linux.
