output gz compression

I am just curious if anybody else has this issue. My platform is OSX 10.4.9 using a custom compiled PHP 4.4.x (4.4.6 & 4.4.7RC1) I've tried using the php.ini setting zlib.output_compression = On and also ob_start("ob_gzhandler"); directly. Each time I call up the page it crashes. On the server side I see this in the error log: [Wed Apr 11 13:57:49 2007] [notice] child pid 10608 exit signal Bus error (10) I even grabbed zlib and compiled that too to try and remedy this. phpinfo says I have 1.2.3: ZLib Support enabled Compiled Version 1.2.3 Linked Version 1.2.3 The best part is that I also have a 5.2.x install and I can use gz output just fine on that build. Any ideas? Thanks!
