tcpkali crashes while load testing

[deleisha]

Hi
tcpkali crashes running following command
./tcpkali --workers 1 -c 1 -T 10s -1 "hello" -m "test" --ssl 127.0.0.1:8000 against

./evt of https://github.com/deleisha/evt-tls/tree/master/sample/libuv-tls
The server(evt) also crashes at OpenSSL layer

Here is the backtrace from the core being dumped on ubuntu 16.04
