I just built OpenSSL 1.0.1 from source using the normal build procedure on

00000000000e2180 T private_AES_set_decrypt_key
00000000000e1eb0 T private_AES_set_encrypt_key
So I'm not sure why they're not global in your case.
Interesting. Thanks for running that.
It looks like a difference in our linkers. Something I just noticed:
In openssl.ld for OPENSSL_1.0.0 it has an entry to make all symbols that
are not explicitly listed local.
global:
BIO_F_ssl;
BIO_new_buffer_ssl_connect;
...
local:
*;
That isn't the case for OPENSSL_1.0.1 however; only the global list is
in place and there's no catch-all local entry. Perhaps that allows for
some freedom for the linker with the symbols that are not listed.
Regards,
Steve
