--- Comment #1 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> --- The failure was not seen on August 9 at https://gcc.gnu.org/pipermail/gcc-testresults/2023-August/793205.html on x86_64-apple-darwin20, so either it is a regression, or the Apple assembler has become more strict between darwin20 and darwin22.
