I'm guessing these are all ENGINEs which were lazily created the first
time they were needed. Notice that they're "still reachable", so
they're not necessarily leaks in the usual sense. Have you tried
calling ENGINE_cleanup()?
The apps.h header in the openssl distribution has a macro which uses
this sequence for shutdown:
CONF_modules_unload(1);
EVP_cleanup();
ENGINE_cleanup();
CRYPTO_cleanup_all_ex_data();
ERR_remove_state(0);
ERR_free_strings();
Other cleanup methods include:
OBJ_cleanup();
COMP_zlib_cleanup();
RAND_cleanup();
....but I'm rather unclear on which need to be called.
