+Subject: [PATCH] lzma: fix buffer bound check error
+
+Variable uncompressedSize references the space available, while outSizeFull is
+the actual expected uncompressed size. Using the wrong value causes LzmaDecode
+to return SZ_ERROR_INPUT_EOF. Problem was introduced in commit afca294. While
+at it add additional debug message.
