Issue #9677 has been updated by Sam Kottler. 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.
