Issue #13094 has been updated by Yui NARUSE.
たしかにFileとZlib::GzipReaderでeof?の挙動が違いますね。
Fileの方にあわせるべきかなぁ……。
さておき、現状こうなってしまっていますし、修正は2.5からだと思うのでgetsの戻り値で分岐した方がよいでしょうね。

Bug #13094: Zlib::GzipReader eof?がfalseなのにgetsでnilが返ってくる
https://bugs.ruby-lang.org/issues/13094#change-62361
* Author: Hironao TSUTSUMIDA
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.4.0preview2 (2016-09-09 trunk 56129) [x86_64-darwin15]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
下記のように、eof?がfalseであればgetsでnilが返ってくることはないことを期待してるとエラーが起きてしまいます。
zlibでeof?は非推奨でしょうか?
~~~ ruby
require 'zlib'
o = ('!'..'~').to_a
i = 225
1000.times do
Zlib::GzipWriter.open('./s.gz') do |gz|
i.times do
gz.write(o.sample(10)*""+"\n")
end
end
Zlib::GzipReader.open("./s.gz") { |gz| puts gz.gets.chomp! until gz.eof? }
puts "#{i}, #{File.size('./s.gz')}"
if File.size('./s.gz') > 2058
i -= 1
else
i += 1
end
end
