Gaminic(1621) It's not just about setting a pointer to 0/NULL. Any pointer that isn't assigned an address is automatically a nullpointer (or at least some type of bad pointer you shouldn't be dereferencing). You should check that every pointer gets assigned an actual address (new, cop...

最主要的原因是在TAU G2中,类或结构体变量都是看作指针的,如果在WATCH窗口看这些变量,在访问变量前,它们都是null,而在赋值之后会显示变量的地址,这和C语言对指针变量的处理基本相同。所以在给这些变量第1次赋值的时候就会报告访问空指针。如果想避免这个问题,就应该在赋值前先使用new关键词分配空间。如: CArray<...
