The following script causes php to segfault when run in CGI mode. The segfaults do
not happen if you remove the output callback function parameter of ob_start(). Please
note that this does not happen when using php4.0.4pl1.
#!/usr/local/bin/php -qe
<?
function compress_output ($output) {
return($output);
}
ob_start("compress_output");
echo "testn";
?>
