base64_decode fails with only one char encoded in base64,

this bug only occurs on Mac OS X (10.7 and 10.8, only versions I currently have 

bug is in PHP in Mac OS X and in actual version from (5.4.6)

I tryied compile with gcc & clang.

Test script:
echo base64_decode(base64_encode("A"))."\n";

Expected result:
<?php echo base64_decode(base64_encode("A"))."\n"; ?>

must returns "A"

<?php echo base64_decode(base64_encode("C"))."\n"; ?>

must returns "C"

Actual result:
<?php echo base64_decode(base64_encode("A"))."\n"; ?>

returns "AD"

<?php echo base64_decode(base64_encode("C"))."\n"; ?>

returns "CD"

what is base64_encode("A") outputs?
 [2012-08-22 19:43 UTC] mail at hanicka dot net
base64_encode("A") returns "QQ=="
 [2012-08-22 20:54 UTC]
That looks correct. So you are saying that base64_decode("QQ==") returns "AD" ?
I really don't see how that is possible.
