PHP Bug Type:     Scripting Engine problem
Bug description:  Function Call in IF ( ) with empty code block causes memory leak

Description:
------------
Empty if that calls a function that returns a value causes php to consume
huge amounts of memory (at least under windows)

This was tested using CLI

Reproduce code:
---------------
function testIt()
{
return true;
}

for ( $ix = 0; $ix < 200000; $ix++ )
{
    echo "Jere is the Memory King $ix" . NL;

    if ( testIt() )
    {
    }
}




Expected result:
----------------
php's memory usage to remain somewhat stable.

Actual result:
--------------
php's memory usage goes up at the rate of about one meg per second while
this script is running.
