[yohgaki@dev php-src]$ cat t.php
<?php
ob_start('foo');
function foo() { ob_end_clean(); }
?>

This kind of code worked since the output buffer was introduced. i.e. Works from
PHP 4.0.
It seems PHP5.4+ has newer API, but it just raise fatal error.
I was surprised now it's not working, so I'll fix this.

Why has the PHP version of the report been changed?
This code works fine in PHP-5.4+

@reeze - thanks for patch & title suggestion.
Is there any way to catch E_PARSE? As you can see ob_* is dead end ;)

@grzegorz129 maybe the title can be more specific: eg: Segfault using
ob_clean/flush* functions in output_callback function

I've sent a pull request to fix this. @see https://github.com/php/php-src/pull/25
this makes php raise fatal error instead of segfault.
This seems to be a logic error when clean/flush output will cause the callback
called and then endless function call.
