这是因为他们可能包含指向内部数据（记录符号和数据类型） 的指针（旧的被GDB 放弃的符号表的一部分）。

This is because they may contain pointers to the internal data recording symbols and data types, which are part of the old symbol table data being discarded inside GDB.

这里将不再描述除了函数、数组、指针和结构体外的新的数据类型。

There is no new constructs you will find in this Module except functions, arrays, Pointers and structures.
