Description:
------------
When I call a function debug_backtrace() in usort() callback, it triggers
unrelated warning.
When i var_dump() it's result, it's OK.
Verified on my mashine
$ php -v
PHP 5.3.11-dev (cli) (built: Mar 1 2012 16:31:39)
and on my friend's mashine with 5.3.5
Test script:
---------------
<?php
error_reporting(E_ALL | E_STRICT);
$versions = array('1', '2');
usort($versions, function ($me, $him) {
debug_backtrace(FALSE);
return 1;
});
Expected result:
----------------
No warning
Actual result:
--------------
Warning: usort() [function.usort]: Array was modified by the user comparison
function in /home/hosiplan/develop/testing/php/backtrace.error.php on line 18
