Description:
------------
Well, reading the manual about empty() you should think it checks
whether the given variable is set before it checks whether it is empty.
(Given example there:
if (empty($var)) {
echo '$var is either 0, empty, or not set at all';
})
However, when $var really is not set, i get a Memory Leak (in a big
script). I reduced the script to the code below and now even get a
Segmentation fault.
Reproduce code:
---------------
<?php
if(empty($foo)){
echo 'empty';
}else{
echo 'not empty';
}
?>
Expected result:
----------------
Echoing "empty" and nothing else.
Actual result:
--------------
Echoing "empty"

Probably most important:

(SIGSEGV)
