--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
I see these failures on darwin10 as well when doing a serial regtesting. They
disappear if the tests are run in parallel (-j2 on a Core2Duo and -j8 on a Core
i7). If I run the test c11-atomic-exec-5.c manually, the run time varies from
~10s on a loaded machine up to more than 50 minutes on an idle one (hence the
time out).

Note that the test fails on powerpc*-*-*, e.g., on powerpc-apple-darwin9:
