Bug description: Crash when using callback with ob_start()
System: Win2000 SP3 (dual CPU if it matters), Apache 1.3.26 (default
setup), and PHP 4.2.3 as a module (default setup)
Problem: When I use ob_start('callback') and "callback" takes $var as its
parameter, Apache crashes if you modify $var and reassign it to $var.
Code:
<?php
ob_start('test');
echo 'This is a test!';
function test($output)
{
$output = strtoupper($output);
return $output;
// Use this instead of the above and it works
$test = strtoupper($output);
return $test;
}
?>
It seems that an Apache child thread can process the script once before it
crashes the child process. e.g. Refresh within KeepAliveTimeout seconds
and it will crash; or with KeepAlive Off, it crashes after ThreadsPerChild
requests.
The "Apache.exe has generated errors..." box pops up. The only thing in
Apache's error log is
[info] master_main: Child processed exited prematurely. Restarting the
child process.
I have the "Dr. Watson" crash log file that was generated if it's of any
use: http://www.realplain.com/phpcrash.txt
BTW, that's weird; I just closed some apps that I usually have running so
their processes wouldn't show up in that log and now I can't get the above
script to crash every time (or at all!) like I could a few mins ago.
Hmm... So don't know if you can reproduce it. However, the script where I
originally noticed it is still crashing consistently as before.
Thanks for your time.
