Description:
------------
When using a memory stream and the read filter "convert.base64-encode" the last character is missing from the output if the base64 conversion needs padding bytes.
This doesn't happen when using a file.

Test script:
---------------
$testString = 'test';
$stream = fopen('php://memory','r+');
fwrite($stream, $testString);
rewind($stream);
$filter = stream_filter_append($stream, 'convert.base64-encode');
echo "memoryStream = " . stream_get_contents($stream).PHP_EOL;


$fileStream = fopen(__DIR__.'/base64test.txt','w+');
fwrite($fileStream , $testString);
rewind($fileStream );
$filter = stream_filter_append($fileStream , 'convert.base64-encode');
echo "fileStream = " . stream_get_contents($fileStream ).PHP_EOL;


Expected result:
----------------
memoryStream = dGVzdA==
fileStream = dGVzdA==


Actual result:
--------------
memoryStream = dGVz
fileStream = dGVzdA==

This bug appears to have regressed, at least in PHP 5.6.12.

The original test case posted with this bug report shows the same broken behavior when tested in 5.6.12.

@mrubinsk:
I looks to be behaving correctly as of 5.6.5. https://3v4l.org/jr2Mi Can you be more specific about how/where it's failing?
 [2015-08-19 19:54 UTC] mrubinsk at horde dot org 
Hm. It appears to work correctly on 3v41.org. Perhaps it's a bug in the debian package:

echo phpversion() . "\r";
$testString = 'test';
$stream = fopen('php://memory','r+');
fwrite($stream, $testString);
rewind($stream);
$filter = stream_filter_append($stream, 'convert.base64-encode');
echo "memoryStream = " . stream_get_contents($stream).PHP_EOL;


$fileStream = fopen('/tmp/base64test.txt','w+');
fwrite($fileStream , $testString);

Results:

5.6.12-1+deb.sury.org~trusty+1
memoryStream = dGVz
fileStream = dGVzdA==
