This is not how C++ works. An object has an address, and that address never
changes as long as the object lives.
But that object can internally contain pointers to store information, and if
it requires more memory, then the object can change that pointer. But the
address of the object itself remains the same.
So is that what I observe something like undefined behaviour or do calls like
"dof_handler.distribute_dofs(fe)" or "triangulation.execute_refinement()"
indeed don't change the address of the underlying triangulation (dof_handler)
in memory?
Correct. They don't change.
