checked_delete问题: Beyond the C++ STL: an introduction to boostdeleter::do_it

环境：

Visual studio 2017

boost库编译选项： msvc141,multi,win64,debug,shared

demo工程设置: debug, win32

问题源:

《Beyond the C++ STL: an introduction to boost》书上Part I, Library 3， checked_delete章节

如果把 deleter.h, deleter.cpp, to_be_deleted.h三个文件内容整合到一个文件里，

编译后会提示 " warning C4150: 删除指向不完整“to_be_deleted”类型的指针；没有调用析构函数"

运行后调用 deleter::do_it  时会间接调用到 ~to_be_deleted()。

调用 deleter::delete_it  时则不会间接调用到 ~to_be_deleted()。

最后调用完 ~to_be_deleted()程序结束时才报一个异常错误。

很奇怪的地方啊！看来是编译器工作方式的不同导致的吧。。。

// deleter.hclass to_be_deleted;class deleter {public:void delete_it(to_be_deleted* p);void do_it(to_be_deleted* p);};// deleter.cpp//#include "deleter.h"#include "boost/checked_delete.hpp"void deleter::delete_it(to_be_deleted* p) {delete p;}void deleter::do_it(to_be_deleted* p) { boost::checked_delete(p);  // typedef char type_must_be_complete[sizeof(T)]; 所有代码放入一个文件，这句居然能编译通过??}// to_be_deleted.h#include <iostream>class to_be_deleted{public:~to_be_deleted() {std::cout <<"I'd like to say important things here, please.";}};// Test application//#include "deleter.h"//#include "to_be_deleted.h"int main() {to_be_deleted* p = new to_be_deleted;deleter d;d.delete_it(p);d.do_it(p);}
