Hi,

 

I am getting a Segmentation Fault in the function:

 

 

The backtrace is here:

It seems that the crash is at function: SSL_connect()-> SSL_set_ssl_method
()

 

 

I have set the CURLOPT_VERBOSE to debug. And on the terminal, it comes:

At this moment, the PEER authentication (CURLOPT_SSL_VERIFYPEER) is set to
false.

 

 

I am using libcurl C Interface (curl-7.16.0) with openssl (0.9.7a)

 

If anyone has any pointers, please let me know.
