ruby -v: ruby 1.9.1p0 (2009-01-30 revision 21907) [i686-linux]

"a,\"b\n\",c\r\n" を CSV.new に渡すとエラーになります。

$ ruby -v -rcsv -e 'p CSV.parse("a,\"b\n\",c\r\n")'
ruby 1.9.1p0 (2009-01-30 revision 21907) [i686-linux]

        from -e:1:in `<main>'

1.8.7 ではエラーになりません。

$ ruby -v -rcsv -e 'p CSV.parse("a,\"b\n\",c\r\n")'
ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]
[["a", "b\n", "c"]]
