Subject: [PATCH] Fix bug in UZbunzip2() that incorrectly updated G.incnt.
|
||
|
|
|
||
|
|
The update assumed a full buffer, which is not always full. This
|
||
|
|
could result in a false overlapped element detection when a small
|
||
|
|
bzip2-compressed file was unzipped. This commit remedies that.
