Trying to clean the buffer in a custom error handler causes script exit when that buffer has 'ob_gzhandler' as a handler. The behaviour is consistent for both PHP5 and PHP4. Note that the example works correctly if there is no callback function specified in the call to ob_start(). 

Reproduce code:
// set error handler
function errorHandler($code,$string,$filename,$line,$scope) {
    die('should reach here');

// use ob_gzhandler to buffer page
echo 'some output';
trigger_error('encounters error',E_USER_ERROR);

Expected result:
should reach here

Actual result:
No output.

Cannot reproduce.
I get no crash, but the expected result instead.

Apologies, on closer inspection this seems not to be a problem with PHP, as it produces the expected results when run from the command line.
