undefined reference to `operator delete(void*, unsigned int)'

Hi,

The following C++ code doesn't link in Crossworks for ARM 3.7.7, with the GNU++14 option selected:

---------- THE CODE -----------

class Something
{
public:
    virtual ~Something() {}

    virtual void Do_Something() = 0;
};

class More_Something : public Something
{
public:
    ~More_Something() {}

    void Do_Something() override {}
};

More_Something something;

------------ THE ERROR MESSAGE -----------

Firmware ARM Debug/main.o: In function `Something::~Something()':

undefined reference to `operator delete(void*, unsigned int)'

Firmware ARM Debug/main.o: In function `Something::~Something()':

undefined reference to `operator delete(void*, unsigned int)'

Firmware ARM Debug/main.o: In function `More_Something::~More_Something()':

undefined reference to `operator delete(void*, unsigned int)'

Firmware ARM Debug/main.o: In function `More_Something::~More_Something()':

undefined reference to `operator delete(void*, unsigned int)'

----------

If I remove the "virtual" from the base class, everything links just fine, but I don't want to do that since that would lead to broken and/or non platform independent code.

Another way around the problem seems to be to add the following line in the base class:

void operator delete(void *) { assert(0); }

But as I want to keep this part of the code platform independent, I wouldn't like to do that either.

Is there a way around this issue?
