Chapter 7 image : page 95 Why is it different from the calling status in the book?

Hi …!

on page 94

It is shown in the call stack “__38- [UnixSignalHandler appendSignal: sig:] _ block_invoke”.

continue program execution
"Go past this by continuing the debugger.
Next you ’ll hit a breakpoint in: "

It doesn’t stop on the call stack below.
I want to know why different,
“__38- [UnixSignalHandler appendSignal: sig:] _ block_invoke_2”

My status stops at file UnixSignalHandle.m: line 127.

In this state, continue …
Stop at line 140

So different content is output to the frame variables.
What is the problem?

My environment is
macOS: Catalina 10.15
Xcode: 11.1 (11A1027)
That’s it.
