--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-08-06 14:30:31 UTC --- Thanks very much. For this sort of test it doesn't need to fail every time, the GCC testsuite is run often enough on a wide enough variety of systems that even if the test only fails occasionally it will be good enough to catch regressions.
