This issue was solved with changeset r43481.
Hiroshi, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.
* ext/openssl/ossl_pkey_ec.c: Ensure compatibility to builds of
OpenSSL with OPENSSL_NO_EC2M defined, but OPENSSL_NO_EC not
defined.
* test/openssl/test_pkey_ec.rb: Iterate over built-in curves
(and assert their non-emptiness!) instead of hard-coding them, as
this may cause problems with respect to the different availability
of individual curves in individual OpenSSL builds.
[ruby-core:54881] [Bug #8384]
Thanks to Vit Ondruch for providing the patch!
* test/openssl/test_pkey_ec.rb: Skip tests for "Oakley" curves as
they are not suitable for ECDSA.
