In practice only a slight change here and there - might result in huge changes. 'Almost identical' but the things that are not identical will screw you up. Almost identical is like 'totally different' in this case. Instead wasting time comparing the machines, he should find the culprit for the segfault. KDE's backtracking tool (drkonqi) and strace help a lot with that. If he knows where it fails, he at least has a chance to find out why.
