Specify that the default initialization must always be done for CDOhash_map's data field. Without doing this, there exists a loop where uninitialized data can be read. This can happen if T is a type like bool. The trace goes: CDOhash_map::set(data) calls ContextObj::make_current(). Now (d_pScope->isCurrent()) is false. So ContextObj::make_current() calls ContextObj::update(). ContextObj::update() calls CDOhash_map::save(). CDOhash_map::save() calls return new(pCMM) CDOhash_map(*this) which calls the copy constructor which reads the data using d_data(other.d_data).
