From: Artem B. Bityuckiy <[email protected]>
In the deflate_[compress|uncompress|pcompress] functions we call the
zlib_[in|de]flateReset function at the beginning. This is OK. But when we
unload the deflate module we don't call zlib_[in|de]flateEnd to free all
the zlib internal data. It looks like a bug for me. Please, consider the
attached patch.
