Fifo<>::Element is missing a virtual destructor

[Stefan Thöni]

Hi Genodians

I would like to create a hierarchy of classes on top of Fifo<>::Element
so these object can be stored in fifos:

class A : public Fifo<A>::Element
{
  virtual method() = 0;
};

class B : public A
{
  method() override { ... }
};

This won't compile because Fifo<>::Element is missing a virtual destructor.

Is there any reason for this? What do you think about adding the virtual
destructor to Fifo<>::Element?


Kind regards
Stefan
