Could you tell me any situation not to use virtual destructor? Usually I use
virtual destructor in derived classes.
This might related embedded C++ software.
Thanks.

In emdedded environment, the resource is quite limited, e.g., the memory.
Make a virtual dtor will add a ptr to vtbl in each class instance. This
comsumes lots of memory if there are thousands of instances.
