Please provide such script that actually has a loop. Simple test
suggested this is just expected and memory does not really grow after
certain point.

Description:
------------
Memory used by the eval() function is not null and can be important (up
to 8Ko) especially if the string is not evaluable.
This memory used can't be released.
Used in a big loop, the memory used is growing up and I get a memory
error.
Reproduce code:
---------------
$result="";
$memory_used1 = memory_get_usage();
$ch="\$result=22;"; if (@eval($ch)===false) {$result = $ch ;}
$memory_used2 = memory_get_usage();
echo "result=$result ==><b>memory difference =
".($memory_used2-$memory_used1)."<BR></b>\n";
$memory_used1 = memory_get_usage();
$ch="abcdef"; if (@eval($ch)===false) {$result = $ch ;}
$memory_used2 = memory_get_usage();
echo "result=$result ==><b>memory difference =
".($memory_used2-$memory_used1)."<BR></b>\n";
Expected result:
----------------
result=22 ==>memory difference = 0
result=abcdef ==>memory difference = 0
Actual result:
--------------
result=22 ==>memory difference = 200
result=abcdef ==>memory difference = 7480
