The code is invalid
MyStream::
MyStream ()
: std::iostream (&m_buf),
m_buf ()
{
}
m_buf has not been cosntructed when you pass it to the base constructor, so
m_buf.init() is called on an uncosntructed streambuf.
You shoudl either pass a null pointer to the base class, then call m_buf.init()
in the MyStream constructor body, or use the base-from-member idiom to
initialise m_buf before the base class.
