Description:
------------
This is an incorrect use of output buffering stuff okay ... but i don't think 
segfaults are a feature.

Test script:
---------------
function handler($message) {
  ob_end_clean();
  echo $message;
}

ob_start('handler');

echo "foo";

Expected result:
----------------
foo

Actual result:
--------------
segfault

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
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

I can't reproduce this on any machine I have to hand, so a backtrace is definitely going to be needed here.
