>Description:
g++ doesn't recognize ios as a virtual base class. The problem is the same if I include <ios> instead of the typedef at the top, but the preprocessed file would be much larger. :-)

The problem goes away, if I substitute the initializer std::ios by basic_ios<char> in the c'tor of Derived.
