You can try building strace for the target. Or you can try to collect more data by building busybox on desktop machine, with same .config, and test it. IOW: we need more data points. -- vda </pre> </blockquote> Believe me, I understand.š "It's broke" isn't very helpful.š If I get a chance to compile strace for my arch, I'll provide the log.š Would it really be useful to get an strace off my desktop since that's a different compiler, etc.? - Coleman </body> </html>
