C++ 垃圾收集、模板和运算符覆盖 - 无法理解为什么会抛出错误

Question

我正在尝试编译一个文件，该文件定义了一个垃圾收集模板和几个使用运算符重载的支持类。我试图通过 MSVC++ 2008 运行它，编译在这个特定的类停止:

// (The collector defines gc_object_generic_base which
// inherits from gc_object_generic_base and optionally adds
// collector-specific properties.)

template<class garbage_collector>
class gc_object_base : public garbage_collector::gc_object_collector_base {
public:
    gc_object_base() {
        garbage_collector::constructing_gc_object_base(this);
    }

    static void* operator new(size_t sz,
        block_construction_locker_base* lock = block_construction_locker<garbage_collector>().get_this())
    {
        return garbage_collector::allocate(sz, lock);
    }
    static void operator delete(void* p, block_construction_locker_base* lock) {
        return garbage_collector::deallocate(p);
    }
    static void operator delete(void* p) {
        return garbage_collector::deallocate(p);
    }

private:
    // TODO: are arrays worth implementing?
    static void* operator new[](size_t sz) {
        assert(0);
        return 0;
    }
};

为简洁起见截断输出:

关于我应该从哪里开始研究的任何想法？

Answer 1

我只是在不同的项目中遇到了相同的错误模式。当有人在某个地方这样做时，它似乎会发生:

#define new new(someArgs, someMoreArgs, etc)

它针对的是简单的"new"表达式，但如果有人试图声明任何更多“运算符新”的东西，它就会崩溃。
