Jem answer is a little more simpler than this solution. But it is possible to substitute the use of a preprocessor macro with the use of templates. Something like this (more refinements you could made):

template 
class CatchWrapper
{
public:

    static void WrapCall(T* instance)
    {
        try
        {
            (instance->*FUNC)();
        }
        catch (std::bad_alloc&)
        {
            // Do Something 1
        }
        catch (std::exception& e)
        {
            // Do Something 2
        }
        catch (...)
        {
            // Do Something 3
        }
    }
};


class Foo
{
public:
    void SomeCall()
    {
        std::cout << "Do Something" << std::endl;
    }
};


int main(int argc, char* argv[])
{
    Foo i;
    CatchWrapper::WrapCall(&i);
    return 0;
}
