Reproduce code:
---------------
for($i=0 ; $i<5000 ; ++$i){
addcslashes("12345","'") ;
echo memory_get_usage(),"<br>\n" ;
}
Expected result:
----------------
The memory usage should be the same in every iteration.
Actual result:
--------------
The memory usage keeps growing and growing up to a certain maximum which
depends on the length of the first argument of addcslashes.
