I would start with a HelloWorld. If that works I would gradually move
stuff from the test into the HelloWorld until I could replicate the
problem. That process might identify what is causing the problem.

std::setw is a pretty simple inlined mechanism. It does nothing but
set a integral variable in the ios_base. This may be a red herring.
