I agree with it, such way is suitable than my hack.

Bug #4879: test_new(OpenSSL::TestPKeyRSA) fails on Win32

こんばんは。
opensslのtest_pkey_rsa.rb:48 がfailします。Visual C++10 を利用しています。

  1) Failure:
test_new(OpenSSL::TestPKeyRSA) [C:/Users/arton/Documents/ruby/trunk/test/openssl/test_pkey_rsa.rb:48]:
<[]> expected but was
<["error:0906D06C:PEM routines:PEM_read_bio:no start line"]>.

このエラーは数回試しましたが常に発生します。
ところが、ここでテストしているRubyをインストールして同じ処理を実行すると期待している結果が得られます。
irb(main):001:0> require 'openssl'
=> true
irb(main):002:0> key = OpenSSL::PKey::RSA.new 512
=> -----BEGIN RSA PRIVATE KEY-----
MIIBOgIBAAJBAMuc7mPnOVmPweq1XMZrOZaOMVoTCX88fsU4460qF0me4S+yGL90
(省略)
-----END RSA PRIVATE KEY-----

irb(main):003:0> pem  = key.public_key.to_pem
=> "-----BEGIN PUBLIC KEY-----\nMFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAMuc7mPnOVmPweq1
XMZrOZaOMVoTCX88\nfsU4460qF0me4S+yGL902+yR5Gv2R6B4QvE5EnxGY5zD9t355+IKaQMCAwEAAQ

irb(main):004:0> OpenSSL::PKey::RSA.new pem

-----END PUBLIC KEY-----

irb(main):005:0> OpenSSL.errors
=> []

もしかすると、test_newの前にエラーが設定されていてそれが読まれているのかと思って、次のようにtest_newを変えて実行したところ、
  def test_new
    $stderr.puts OpenSSL.errors.inspect
    $stderr.flush
    key = OpenSSL::PKey::RSA.new 512
    pem  = key.public_key.to_pem
    OpenSSL::PKey::RSA.new pem
    assert_equal([], OpenSSL.errors)
  end

上のように修正するとfailしなくなりましたが、取得されるエラーは以下でした。これも数回試しましたが常に同じメッセージです。
.........................................................["error:0D07803A:asn1 e
ncoding routines:ASN1_ITEM_EX_D2I:nested asn1 error"]...(省略)

OpenSSLは1.0.0aです。

irb(main):001:0> require 'openssl'
=> true
irb(main):002:0> OpenSSL::OPENSSL_VERSION
=> "OpenSSL 1.0.0a 1 Jun 2010"

よろしくお願いします。
