On AVR target g++ generates code which copies object’s VTABLES from FLASH
to SRAM wasting the memory. Due to the Harvard architecture of AVR processors
the solution is not trivial. This behavior can be observed in any c++ program
which has object with virtual method, e.g:
Class test
{
virtual void example();
};
The VTABLE of class test will be generated in FLASH and next copied to SRAM,
any reference to virtual example() method will take the method address from
SRAM.
