The m_typedConfigurations pointer is copied from one object to the next, but deleted in the dtor, leading to potential double free. It is also deleted first thing in the copy ctor, deleting uninitialized memory. This does not seem to actually happen in practice (those functions do not get called), but seems safer that way.
