commit e4f77bf1833245d2b6aa4ce6a16c85e1cdf78589 Author: Matt Caswell <matt@openssl.org> Date: Thu Apr 23 20:01:33 2015 +0100 Add Error state Reusing an SSL object when it has encountered a fatal error can have bad consequences. This is a bug in application code not libssl but libssl should be more forgiving and not crash.
