Thanks, but I couldn't reproduce, and I suspect it's because the
recipe is not well-defined.  Let me ask some questions.

Thanks for looking into it! I retested with emacs -Q test.txt, along with the clarifying steps provided below, and could reproduce.

So hopefully there should be sufficient information.

4. Make sure display-line-numbers-mode is turned on, and set wrapping

mode to word wrap

D|oes this mean turn on visual-line-mode, or does this mean just
assign value to word-wrap?

Turn on visual-line-mode.

5. Put cursor on last word of second line, ("subgaussian"), and zoom in 
until second line just spans two lines

What does it mean "just spans two lines"?  What exactly should appear
in the last line of the buffer?

"-subgaussian"

Also, what is the size of the frame where this recipe should be run?

(set-frame-size (selected-frame) 171 35)

6. M-x split-window-right

And Emacs freezes right after split-window-right?  Or do I need to do
anything else?

Yes, it freezes right after split-window-right. On htop I observe it using 100% CPU, and increasing memory usage.
