=begin
While I realize this is probably wrong, I was trying to find a cipher that JRuby 1.7.4 supported and encountered this crash.

My OpenSSL version is:

  $ ruby -ropenssl -e 'p OpenSSL::OPENSSL_VERSION'
  "OpenSSL 1.0.1e 11 Feb 2013"

The crash:

  $ ruby crash.rb 
  crash.rb:10: [BUG] Segmentation fault
  ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0]
