@see tests/output/ob_011.phpt there is a XFAIL
In PHP5.4 using ob_* functions in output_callback will issue Fatal error, but in 5.3 only calling ob_start() function will raise Fatal error ,but calling ob_clean/flush* functions will cause Segfault because of the endless recurse function call.
maybe the patch isn't perfect, please don't hesitate to let me know.
