Then depending on what gets output you know in which half of the problem space the error exists. Then you take again divide the problem space until you find the exact location of the bug. > I suppose it is possible that it's dying at some point other than where the > output is stopping.

I didn't realize you had already tracked down the location. Have you tried displaying errors? If you're worried about a production site you could install a custom error handler that displays the error based on the REMOTE_ADDR value. That won't help you though if a segfault is occurring. Are the PHP versions the same between machines?
