Using the stub code below, I get the following error when running phar file:

Fatal error:  Out of memory (allocated 786432) at /php5/ext/phar/phar_object.c:96 (tried to allocate 4294967283 bytes) in /var/www/html/app.phar.tar.php on line 4

Reproduce code:

$a->setStub("<?php
function rw(\$a) { return '/html/index.php'; }
Phar::interceptFileFuncs();
Phar::webPhar('$file.phar', '/html/index.php', null, array(), 'rw');
echo 'ZFApp is intended to be executed from a web browser\n';
exit -1;
__HALT_COMPILER();
