代码中是用assign来 str.assign(str2)，str2 是通过rapidjson GetString()获得， basic_string.h头文件内容中声明basic_string& assign(const basic_string& __str);
#include <ext/atomicity.h>
#include <debug/debug.h>
#if __cplusplus >= 201103L
#include <initializer_list>
#endif
/**
* @brief Set value to contents of another string.
* @param __str Source string to use.
* @return Reference to this string.
*/
basic_string&
assign(const basic_string& __str);
basic_string.h 中 #include <debug/debug.h>， 在debug.h中找到assign定义
basic_string&
assign(const basic_string& __x)
{
_Base::assign(__x);
this->_M_invalidate_all();
return *this;
}
str析构的时候崩溃
