--- Comment #9 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-10-24 19:33:32 UTC --- I'm not sure if these failures are due to PR 50598: FAIL: 30_threads/thread/native_handle/typesizes.cc execution test FAIL: ext/mt_allocator/deallocate_global_thread-1.cc execution test FAIL: ext/mt_allocator/deallocate_global_thread-3.cc execution test The first one might be due to the dg-options for *-*-darwin not including -pthread (which I believe should be valid on both x86 and ppc darwin)
