Wrong status...

Could you provide us a short and self-contained example script to reproduce this problem?

The following code is a short form of what I have
in the production environment. Switching back and
forth between buffercompression on and off makes
it crash. It seems only to happen when compression
is on. Unfortunately it does not happen all the time.
I could not find out under which condition it crashes
but it happens very frequently. Around every third 
or fourth reload. Sometimes with the tenths ;-). If
you wait a longer time between reloads it seems to
happen every time. Could it be something with the
cache or the buffer in memory itself?

The output of the variable which contains the
status seems not to have something to do with it.
When I remove the var_dump it also crashes.

$outputbuffering = true;
$buffercompression = false;

function start_buffering(){
	global $outputbuffering,$buffercompression;
	if ($outputbuffering == true AND $buffercompression == true){
		ob_start("ob_gzhandler");
	}elseif ($outputbuffering == true AND $buffercompression == false){
		ob_start();
	}

function stop_buffering(){
	global $outputbuffering;
	if ($outputbuffering == true){

}
start_buffering();
print "Hello World<BR>";
stop_buffering();

I monitored the memory behaviour of Apache. You could
say I gave myself a hint ;-)))

When I reload the script, whether compression is on or
of, and make Apache crash, it restarts itself again
and shows the output.

When I wait a couple of seconds I can see a change of
4K in the memory usage of Apache. When I reload then
it always crashes. When I reload before this memory
change occurs, it does not crash.

I can reproduce this problem with 4.2.3 but not with 4.3.0 or later version. So this may be fixed in the latest released version (4.3.0). Could try that one?

With PHP 4.3.1 this error does not occur anymore. Also
the 4KB memory change in Apache has gone.

Thank you for your bug report. This issue has already been fixed
in the latest released version of PHP, which you can download at
