Compression routine reads past the end of the array

[GoogleCodeExporter]

Hello,

It appears that there is an issue with the compression routine reading past the 
end of the array for certain inputs.

Please see the attached fuzz test. It will crash on the second iteration.

The version used in this test is too old.
By updating lz4.c & lz4.h to latest available version (currently r57), problem 
disappears.

I guess you probably downloaded the older version by using the "download 
package" option. Unfortunately, Google Code is not able to automatically update 
such package currently.

In order to avoid future issue, i will remove the link from the download page.

You're right, thanks! The latest version appears to work perfectly.
