I still have this issue, even with 7.40.0:

    ~/src/curl-7.40.0/src $ ./curl https://qasecommerce.cielo.com.br/servicos/ecommwsec.do -v --tlsv1
    * Trying 201.18.41.183...
    * Connected to qasecommerce.cielo.com.br (201.18.41.183) port 443 (#0)
    * successfully set certificate verify locations:
    * CAfile: /etc/ssl/certs/ca-certificates.crt
      CApath: none
    * TLSv1.2, TLS handshake, Client hello (1):
    * Unknown SSL protocol error in connection to qasecommerce.cielo.com.br:443
    * Closing connection 0
    curl: (35) Unknown SSL protocol error in connection to qasecommerce.cielo.com.br:443

It works fine on older versions like 7.22.0 on Ubuntu 12.04:

    $ curl https://qasecommerce.cielo.com.br/servicos/ecommwsec.do -v --tlsv1
