Not with presented information :-( You need to complement it with output
from 'info reg' as well as output from 'disass' command till you see =>
mark pointing at failing instruction. From debugger prompts that is. And
since stack back-tracing is problematic here, tell approximately what
was going on? I mean did you experience crash with openssl command
(which one if so), or is it a web (or some other tls) server facing network?

It was incorporated 1.0.1 since 1.0.1f.
