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

Once you have generated a backtrace, please submit it to this bug

us make PHP better.

Also make sure you don't have any Zend modules (zend_extension) loaded.
