Ok, thx. After the following additions to the said sample the mem-leaks disappear:

#include <openssl/engine.h>

// extracted from the macro "apps_shutdown()" in file openssl/apps apps.h
void my_libcrypto_shutdown()
   {
     CONF_modules_unload(1);
     EVP_cleanup();
     ENGINE_cleanup();
     CRYPTO_cleanup_all_ex_data();
     ERR_remove_state(0);
     ERR_free_strings();
   }

// at the end of the app call this:
my_libcrypto_shutdown();
