Hi all,

I am using curl library 7.20.1 and ssh2 library 1.3.0 on x86 platform with
centOS.

I have a remote server that is password less, it's OS is installed in such
a way that it won't prompt for password at all for any kind of logins
including ssh.
I am trying to upload/download a file from/to remote server from my host
machine(with above mentioned config). On the URL to curl API, I am passing
a junk password in the password field.
I am facing crash in ssh2 api. following is the core assessment.

-- Program terminated with signal 11, Segmentation fault.

#7 0xf7e9c3cc in curl_easy_perform (curl=0xbabb4bc) at easy.c:556

what could have gone wrong here? is there a fix for this?

thanks,
madhu
