I am using
http://www.openssl.org/docs/crypto/threads.html
to make crypto library thread safe. It is working find if I am linking with static library of libssl and libcrypto.
But if I am linking with dynamic version of the library and running multiple instance of the binary it is crashing.
How to fix this issue ?
Edit
Program is always crashing at
