Have you read the documentation on using libcurl with threads and are you
following all the recommendations? Specifically, are you calling
curl_global_init in your main thread first and are you setting the
OpenSSL locking functions?

This looks like a serious problem--there should never be any internal
errors. What libcurl operations are occurring in other threads while
this one runs? Can you show us the source code to a program that can reliably
reproduce this?

These are both fairly old versions. Have you tried newer versions to see if you
still have issues?
