McClain, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.
- ext/zlib/zlib.c (zstream_run): Fix handling of deflate streams that
need a dictionary but are being decompressed by Zlib::Inflate.inflate
(which has no option to set a dictionary). Now Zlib::NeedDict is
raised instead of crashing. [ruby-trunk - Bug #8829]
- test/zlib/test_zlib.rb (TestZlibInflate): Test for the above.
- Tracker changed from Bug to Backport
- Project changed from Ruby master to Backport200
