This is causing failure on x86 (32-bit) Debian 8 and FreeBSD 11.0 (amd64).
Seems OK on amd64 Debian 8.

  1) Failure:
TestZlib#test_gunzip [/path/to/ruby/test/zlib/test_zlib.rb:1194]:
[Zlib::GzipFile::NoFooter] exception expected, not.
Class: <Zlib::GzipFile::Error>
Message: <"unexpected end of string">
