Hi Openssl is crashing within calls of libcurl. The stack trace for your reference. :-

No I tried to look for some answers and found this thread(namely locking_function and threadid_func):- http://curl.haxx.se/docs/faq.html#Is_libcurl_thread_safe This gives pointers to examples in Solaris and Win32 examples for certain callback handlers needed for correct thread safe usage. Now I didnt browse through curl source but I believe that these callback handlers must be implemented in curl_global_init(). Is there any other location I should put these handlers(I mean write the implementation somewhere?). More importantly, I don't quite understand why curl didn't handle this in their baseline implementation?
