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.
