c – 为什么这有效？这是一个小例子,但它甚至可以用于更复杂的项

#include <cstdio>
class baseclass
{
};

class derclass : public baseclass
{
public:
    derclass(char* str)
    {
        mystr = str;
    }
    char* mystr;
};
baseclass* basec;

static void dostuff()
{
    basec = (baseclass*)&derclass("wtf");
}

int main()
{
    dostuff();
__asm // Added this after the answer found,it makes it fail
{
    push 1
    push 1
    push 1
    push 1
    push 1
    push 1
    push 1
    push 1
    push 1
    push 1
}
    printf("%s",((derclass*)basec)->mystr);
}
