Comment (by alamaison):

 Like #298, these are probably not real leaks. OpenSSL caches various
 pieces of global data that it initialises on demand. Once loaded, it
 caches them for the lifetime of the program. Some even _have_ to be kept
 for security reasons.

 If they are causing a problem by creating false positives when you're
 checking for memory leaks, try calling some of the globally-destructive
 OpenSSL cleanup functions in your application, only when running your leak
 checker or test suite.

 The following works for me:

 {{{
 ::RAND_cleanup();
 ::ENGINE_cleanup();
 ::CONF_modules_unload(1);
 ::CONF_modules_free();
 ::EVP_cleanup();
 ::ERR_free_strings();
 ::ERR_remove_state(0);
 ::CRYPTO_cleanup_all_ex_data();
 }}}
