Description:
------------
getStream() return stream, which allows to read only (4194304) 4MB data. 
The same entry can be successfully extracted to disk using extract() method. 
Archive was tested on different OS, file was extracted using different software all is ok. This second time I'm reporting this because noticed magic number 4194304 which clearly indicates a bug. 

Also uploaded original file to Google Drive. 

Test script:
---------------
<?php

$remote_path = 'https://drive.google.com/uc?export=download&id=0B6ulFGsiVVF3MkhOTGVEYmxhcFU';
$local_path = sys_get_temp_dir().DIRECTORY_SEPARATOR.'buggy.rar';
if(!file_exists($local_path)){
 copy($remote_path,$local_path);
}

$rar = RarArchive::open($local_path);
$rar->setAllowBroken(true);
$entries = $rar->getEntries();

$entry	= $rar->getEntry('08-twisted_sister-deck_the_halls.mp3');
$declared_size	=	$entry->getUnpackedSize();
$declared_crc	=	$entry->getCrc();
$declared_name	=	$entry->getName();

echo "Expected:\t Size:{$declared_size}\tHash:{$declared_crc}\n";

// Extract item to disk
$extracted_path	= sys_get_temp_dir().DIRECTORY_SEPARATOR.'extracted';
$entry->extract(false, $extracted_path);
$extracted_size	= filesize($extracted_path);
$extracted_hash	= hash_file('crc32b',$extracted_path);
echo "Extracted:\t Size:{$extracted_size}\tHash:{$extracted_hash}\n";

// "Stream" file
$stream		=	$entry->getStream();
$stream_path	=	sys_get_temp_dir().DIRECTORY_SEPARATOR.'stream';
$stream_fp	=	fopen($stream_path,'w');
stream_copy_to_stream($stream,$stream_fp);
$stram_size	=	filesize($stream_path);
$stram_hash	=	hash_file('crc32b',$stream_path);
echo "Stream:\t\t Size:{$stram_size}\tHash:{$stram_hash}\n";

echo "\nVery strange number {$stram_size} = ",$stram_size/1024/1024,'MB which clearly indicates a bug',PHP_EOL;
echo "PHP \t",phpversion(),PHP_EOL;
echo "OS \t",php_uname(),PHP_EOL;

exit;

Expected result:
----------------
Expected:        Size:5069304   Hash:a7bab6b3
Extracted:       Size:5069304   Hash:a7bab6b3
Stream:          Size:5069304   Hash:a7bab6b3


Actual result:
--------------
Expected:        Size:5069304   Hash:a7bab6b3
Extracted:       Size:5069304   Hash:a7bab6b3
Stream:          Size:4194304   Hash:51ccf6cb
