Thank you for the fine report. This does sound like a bug... The problem is that you configured and built on one type of system and ran the executables on a different type. While in general that's ok, there are some configure-time tests that detect OS bugs and work around them (or features, and take advantage of them), and in unusual cases, that can lead to trouble. So if it found/enabled something on the system where built, yet that bit failed (without run-time recourse) on the different system where it was run, ... Obviously, we try not to have many pieces like that, but it can happen, especially when someone builds on a newer system and tries to run the resulting binary on an older one. *That* is not supported at all. But you didn't do that. In your case, if you provide some more info, it may help: - strace one of the losing cp commands (on RHEL4) - strace the same, working cp command (on RHEL3) - lib/config.h from your coreutils build directory on RHEL3 > I believe I reported this quite some time ago.

If not, doing so (and merely referencing this thread: http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/14699) may also accelerate the processes. Also, using the RHEL3 binaries, can you run "make check" on a RHEL4 system to see if any regression tests fail? > The /tmp on my machine is the local drive.
