Hello - and thanks for your answer.

Yes, you're right - I tried to conform to the customer's platform configuration for my tests (and this platform is a very old RedHat version).

I updated OpenSSL to openssl-0.9.8e-22, CURL to curl-7.33.0, I updated my code to have CURLOPT_DEBUGFUNCTION on, and I still have a Segmentation fault...
Here are the DEBUG traces:

DEBUG - Text=About to connect() to cnr-ws.wrc-cnr.gemalto.com port 8083
DEBUG - Text= Trying 10.160.164.123...

The backtrace still is the same:

I'm preparing a test application to do a single https request, without thread, to see if I have the same problem...

curl 7.15.5 was released over 7 years ago on Aug 7th 2006. We have done over
1000 bug fixes since then...
