Please provide:

• a short example that demonstrates the issue
• the output of your remote debug log: http://xdebug.org/docs/remote#remote_log
• a gdb backtrace of the crash: http://bugs.php.net/bugs-generating-backtrace.php (under "If you can't get a core file")

Steps To Reproduce :

parentScript.php:
<?php
echo "Hello World\n";
passthru('php childScript.php');

childScript.php:
<?php

echo "What's up ?\n";

run parentScript.php with Xdebug active.

I cannot get any backtrace, the execution of the script if simply frozen :/

Is this still a problem for you with the latest versions of PHP and Xdebug?

I could not reproduce this, and no feedback was given. I'm closing this issue, but feel free to reopen if this happens again.
