CRYPTO_lock - OpenSSL thread support

    http://openssl.cs.utah.edu/docs/crypto/threads.html
    OpenSSL can safely be used in multi-threaded applications provided that at least two callback functions are set, locking_function and threadid_func. locking_function(int mode, int n, const char *file, int line) is needed to perform locking on shared data structures.

    In short, OpenSSL has always, and only, supported the concept of locking an object and sometimes it locks its internal objects. Read on for more details. In OpenSSL 1.0.2 (and earlier), applications had to provide their own integration with locking and threads, as documented in the threads.pod file.

EC_POINT_mul() creates duplicate keys · Issue #231 ...

    https://github.com/openssl/openssl/issues/231
    Feb 24, 2015 · In a vanity bitcoin generator, OpenSSL thread support enabled and OpenSSL threading configured (i.e. 41 CRYPTO_num_locks), running multiple pthreads with EC_POINT_mul() creates duplicate EC_POINT randomly, i.e. say after ~1000 or so iterations. Each thread has their own EC_GROUP etc, no global variables.
