I added <algorthm> to a standard header file that's included with most files in my project. On a Core2 Duo machine with std=c++11, testing produces the following compile error:

g++ -DNDEBUG -g2 -O2 -std=c++11 -fPIC -march=native -pipe -fsanitize=address -c cpu.cpp

I'm trying to determine how I should proceed.

Is <algorithm> supposed to include AES intrinsics?
