Summary0000087: Warning about headers when "register_shutdown_function" used
Description

When "register_shutdown_function" is used in the code, the following warning is issued:

Warning: Cannot modify header information - headers already sent in Unknown on line 0

All goes well when xdebug.so is not used.
This bug causes PEAR packages to have problems

<?php

function logit($x)
{
$f = fopen("/tmp/logit.txt", "a");
fwrite($f, "$x\n");
fclose($f);
}

function sayonara()
{
}

register_shutdown_function("sayonara");

?>

I can not reproduce this with your code, it works fine. Can you please give me a list of all xdebug related settings that show up in phpinfo() output?

Is this still a problem with the latest CVS version of Xdebug?

Today I've tried the latest Xdebug version and I can reproduce the error, however only using php command line program. PHP module for apache seems to work well. Tried with PHP 5.0 and 4.3.3.
I will be trying to reproduce this at home, on Mandrake Linux 9.1.

I can still not reproduce this, so I'm marking this bug as "unable to duplicate". If you can provide more information, please reopen.

I did see this error when running Xdebug with Komodo, so it seems to be valid. Will need to dig into this though.

I can confirm the bug's existence on the Fedora Core 4 with updates: PHP version 5.0.4, xdebug 2.0.0rc1-dev, Apache/2.0.54 (Fedora).
The same code used to reproduce the bug.
