Tested on PHP-4.1.1 on linux (CLI and Apache2 module) with same error on both. Also tested on PHP-5.0.5 on Win32 (CLI and Apache2 module) with same error on both. Reproduce code: --------------- <?php function nooutput($text) { return ""; } print "Before\n"; ob_start("nooutput"); print "Middle\n"; ob_flush(); ob_end_flush(); print "After\n"; ?> Expected result: ---------------- Before After Actual result: -------------- Before Segmentation fault ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35156&edit=1
