Do you provide mutexes to the library? For multi-threaded applications,
the following calls are required in initialization:
CRYPTO_set_id_callback(id_callback);
CRYPTO_set_locking_callback(locking_callback);
The two callback functions must be provided by the application. Under
Windows, CRYPTO_set_id_callback is not required because OpenSSL knows
about GetCurrentThreadId(); also you can do without
CRYPTO_set_id_callback on those Unix thread implementations where
threads have distinct PIDs, but then you have to expect severe
problems on other implementations where threads created within on
process share one PID.
