--- Comment #47 from John David Anglin <danglin at gcc dot gnu.org> --- I have v18 patch installed into the build infrastructure for the Debian gcc-15-15.1.0 package. I'm still seeing timeouts. For example, WARNING: program timed out. FAIL: gnat.dg/array39.adb execution test I haven't debugged this yet but previous debugging with v15 indicated a problem with tv_nsec field in timespec. This caused pthread_cond_timedwait in the Timed_Sleep procedure to return EINVAL (22). This caused an infinite loop and the timeout in the gnat.dg/array39.adb execution test. There are quite a few patches in the gcc-15-15.1.0 package. I could easily have messed up applying v18.
