Is there anything else I can do to assist? ------------------------------------------------------------------------ [2006-06-20 12:15:20] tony2001@php.net Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2006-06-20 12:13:31] jona at oismail dot com How do I do I get that? If I call either debug_backtrace() or debug_print_stacktrace() prior to calling DOM->schemaValidate(), I get no useful output. If I call either of the backtrace functions after DOM->schemaValidate(), they're never executed due to the PHP Access Violation. Please advice? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
