GDB/C++ - 如何在回溯时隐藏常量静态字段？

Question

我正在使用 gdb 调试 C++ 代码。有些东西在摇晃，所以我点击“backtrace full”进行检查。不幸的是，一些成员变量是包含 const static 字段的 class 的实例。有很多 const static 字段。此外，这些 const static 字段本身就是上述 class:

的实例

class foo {
public:
   int val;
   foo(int _val) : val(_val) {}

   static const foo FOO_5 = foo(5);
   static const foo FOO_6 = foo(6);
   static const foo FOO_7 = foo(7);
   ...
   }

（我的真实代码是字体格式 class，带有粗体、斜体、黑色、红色等预设）

结果是 gdb 感觉需要吐出所述 class 的每个成员的每个 const static 字段（以及每个成员的每个成员，等等）。这会导致许多屏幕显示相同的 const static 字段：
