    The setting is actually called display_errors, not display_error. Make sure this is correct in your PHP configuration.

    Mike's post may be relevant (also regarding a "_debug=1" error):


    A Google search reveals no love for eAccelerator:


    This is a server problem of some kind. You should ask your host or server person about this as well.

    Save the file and open it in a text editor. It might contain an error or something useful.

    Is it even possible to segfault with PHP code? I don't think so given the lack of direct memory management. Hence it has to be a problem with PHP itself, or likely a module in PHP.
