Hello,

I tested on another amd64 machine (CPU without AES support) and there I cannot
reproduce the bug (even not after upgrading libc6 to 2.17-0experimental2).

Kind regards
Benjamin

I and other people who have AES support can't reproduce the
problem, and I don't understand why.

The OPENSSL_ia32cap turned off AESNI support. Bit 57 (the first
2) is the AESNI capability. Not sure why the other bit was asked
to be turned off, that seems to be only relavant for gcm128.
