-Subject: [PATCH] Fix a bug when getting a gzip header extra field with
- inflate().
-
-If the extra field was larger than the space the user provided with
-inflateGetHeader(), and if multiple calls of inflate() delivered
-the extra header data, then there could be a buffer overflow of the
-provided space. This commit assures that provided space is not
-exceeded.
