Bug description: Memory leak when looping an associative array
Description:
------------
When looping numerically through an associative array, certain operations
cause a massive memory leak in Apache, eating up all available ram at
about 60mb/s. Windows grinds to a halt as 1gb of Virtual Memory is
gobbled up.
Trying to echo each element of the array returns nothing as would be
expected, but concatting or executing a function such a stripslashes on
the elements causes the memory leak.
My php.ini differs only in max_execution time and the maximum size of POST
uploads.
Reproduce code:
---------------
$array['a'] = 'Some text';
$array['b'] = "It\'s nice text";
// prints 2
echo count($array);
// prints nothing
echo $array[0];
// does nothing
$array[0] = stripslashes($array[0]);
for ($i=0; $i<count($array); $i++)
{
// does nothing
echo $array[$i];
// memory leak
$array[$i] = 'blah' . $array[$i];
// memory leak
$array[$i] = stripslashes($array[$i]);
}
Expected result:
----------------
To have no effect on the array
Actual result:
--------------
Sorry, I can't decipher your instructions for using backtrace! Shoot the
stupid guy ;o)
