Thank you for your bug report. This issue has already been fixed
in the latest released version of PHP, which you can download at 
http://www.php.net/downloads.php

Will not get fixed in 4.4, but already fixed in 5.2.

php -r 'var_dump(base64_decode("This is short string!", 
true));'
bool(false)

I think this should get fixed in 4.x branch, too, as many people don't want (you can guess why - incompatiblity 4.x/5.x is the thing) or are not able to switch.
