POSIX says that we can't rely on >&- closing stdout; it works on most platforms, but HPUX apparently ignores the request and reopens stdout to /dev/null, and POSIX allows this behavior. The test is too strict, and should be checking whether it is possible to start a program with stdout closed before requiring a particular behavior in that condition (since HPUX has no way to get into that condition). > Curiously, this test behaves as expected on HPUX-11.11 and 11.00. > Safe to ignore? Can the test case be fixed? I'll see what I can come up with today. If I don't come up with a way, then it is safe to ignore. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
