Thanks for the report! I'm looking into this now.

----------------------------------------
Bug #9677: OpenSSL::PKey::EC#to_text causes a segmentation fault
https://bugs.ruby-lang.org/issues/9677#change-46477

* Author: David Grayson
* Status: Open
* Priority: Normal
* Assignee: Martin Bosslet
* Category: ext/openssl
* Target version:
* ruby -v: ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
I have Ruby 2.1.1p76 and when I try to run a particular snippet of code
using the OpenSSL extension, I get a segmentation fault.  I am running
Arch Linux and I have openssl 1.0.1.f-1.  I built Ruby from source.
This bug also affects Ruby 2.1.0.

Here is a snippet of shell output showing the Ruby command that causes
the problem:

~~~
$ ruby -v -ropenssl -e "OpenSSL::PKey::EC.new('secp256k1').to_text"
ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-linux]
-e:1: [BUG] Segmentation fault at 0x00000000000000
...
~~~

I attached a text file with the full output from Ruby to this bug
report.
