haproxy 1.6.0 crashes

[Seri, Kim]

Hi, all

HAProxy 1.6.0 crashes in multiple certificates environment as belows,
   bind :443 ssl crt test.com.pem crt test2.com.pem ecdhe prime256v1

but, in single certificate environment, haproxy doesn't crash.
   bind :443 ssl crt test.com.pem ecdhe prime256v1


after applying commit d2cab92, haproxy seems to crash.

Thanks in advance.
