register_shutdown_function() provides a warning instead of a fatal error when calling an undefined function.  Not sure if this is intentional or not but here's a test script:

<?php
echo 'hello';
register_shutdown_function('do_not_exist');
?>

And next, the strange looking error.  Same result for both Apache module and CLI:

Hello
Warning: Unknown(): Unable to call do_not_exist() - function does not exist in Unknown on line 0

A PHP5 CLI demonstrates this same error.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

When some engine facility tries to call a non existing functions you receive such errors.

I don't understand the answer, and this is certainly not documented.  Also, why did you assign it to yourself and mark it as bogus?

No bug here. Philip, ask such questions on the mailing list and stop spamming the bug system with these..

I'm sorry, I didn't realize that Unknown() and line #0 were  official, I'll add this to the documentation.
