when I tried the example of Zeev Suraski at http://www.zend.com/zend/art/buffering.php, with the php.ini directive output_handler = ob_gzhandler it caused Segmentation fault of the apache.
I tried to use ob_start("ob_gzhandler"); and again segmentation fault ...

here are some tests
$test = ob_gzhandler("test") makes unpredictable results;
$test = gzencode("test") work fine (it even compress the text);
ob_start("gzencode") end with segfault again;

this happend on two different machines (both with debian) but one with a precompiled php debian package the other php compiled from me. both are compiled --with-zlib

phpinfo() gives this

zlib
ZLib Support enabled 
'zlib:' fopen wrapper enabled 
Compiled Version 1.1.3 
Linked Version 1.1.3

well in php4.0.4pl1 this problem seems to disappear
output_handler = ob_gzhandler works fine (even compresses the output :))
