Hello curl's :)

I'm new in the curl world, but I have a problem with it.

I like use curl to connect a ftps server through a proxy (CONNECT), but
I receive a "Segmentation fault" error.

The error is located in file lib/ssluse.c in the line:
  1716: int rc = SSL_write(conn->ssl[sockindex].handle, mem, (int)len);

At the moment of the error the mem variable contains a pointer to string
that contains:

  CONNECT yyy.yyy.yyy.yyy:50004 HTTP/1.0
  Host: yyy.yyy.yyy.yyyyyy.yyy.yyy.yyy:50001
  User-Agent: curl/7.15.5 (i686-pc-linux-gnu) libcurl/7.15.5
OpenSSL/0.9.7a zlib/1.1.4
  Proxy-Connection: Keep-Alive

I think SSL_write shouldn't write this, because one is for send data by
the tunnel, not for establish it.

I get the error using curl/7.15.5 in debian testing, Redhat ES 3 and
Fedora core.

Any suggestions?

Greetings

PD: Sorry, but my english is very poor.
