It seems this commit causes SEGV in openssl tests.

test-all finished before the commit:
http://www.rubyist.net/~akr/chkbuild/debian/ruby-trunk/log/20091107T062200.log.txt.gz

test-all aborted after the commit:
http://www.rubyist.net/~akr/chkbuild/debian/ruby-trunk/log/20091107T094000.log.txt.gz

It is reproducible as follows:
