Environment

• OS: Ubuntu 16.04
• RVM
• Ruby: 2.2.3, 2.3.6, 2.4.2, 2.5.1,
• Curb: 0.8.8, 0.9.6,
• OpenSSL 1.0.2g,
• Curl: 7.47.0

What happens

Killing a thread during Curb::Easy#perform causes segfault. Timeout does that under the hood. Sometimes it happens right after the kill, sometimes on the next garbage collection.

Steps to reproduce

Install ruby 2.5.1 through rvm. Start proxy.sh Start curb_fail.rb
