[xmlsec] Re: Leaks memory in version 0.0.14. Help me! Thank you.

I am not sure I can help you without information "where the memory leak is".
Anyway, it seems that you did not cleanup OpenSSL completely. Try to add
the following lines at the very end:

    #ifndef XMLSEC_NO_X509
        X509_TRUST_cleanup();
    #endif /* XMLSEC_NO_X509 */
                                                                               
    #ifndef XMLSEC_OPENSSL_096
        CRYPTO_cleanup_all_ex_data();
    #endif /* XMLSEC_OPENSSL_096 */
                                                                               
        /* finally cleanup errors */
        ERR_remove_state(0);
        ERR_free_strings();
