That isn't an assignment, it's a copy construction.

This is exactly equivalent.

The error seems to indicate a race condition in the initialization of
the std::ios_base base class.  I've seen someone report a similar
error in that libstdc++ code before, but I think it's correct (I can't
see a problem anyway) so it could be user error, but I'm not sure.
