I tried it, but applying the option --gc-sections results in an empty
executable file. Am I missed something? Without it everyting works in the
known way.
BTW I wanted to try what happens if those functions are virtual and the
mentioned options are used. I know that using virtual functions have its
cost, but I don't know its couple to the operator delete(). Of course I will
avoid using them as far as it is possible, but I want to know their behavior.
