Calling apc_store two times in a row with the keys "75" and "6V" issues a "Potential cache slam" warning, although the keys aren't the same.

Reproduce code:

$s1 = '75';
$s2 = '6V';

apc_store($s1, 1);
apc_store($s2, 2);

echo apc_fetch($s1) . "\n";
echo apc_fetch($s2) . "\n";

Expected result:

Actual result:
Warning: apc_store(): Potential cache slam averted for key '6V' in /home/seb/tmp/apc.php on line 7

APC's apc_store() has been superseeded by APCu's apcu_store().
Does this issue still occur using the latter?
