echo-nginx-module and HTTP2

[A. Schulze]

Hello,

The echo module (https://github.com/openresty/echo-nginx-module / v0.58)
produce segfaults while accessing the following location:

    # echo back the client request
    location /echoback {
      echo_duplicate 1 $echo_client_request_headers;
      echo "\r";

      echo_read_request_body;

      echo_request_body;
    }

that happen only if http2 is enabled (usually at https servers).
