Press RET on the line again. It doesn't crash for me here.

(You will need to source src/.gdbinit for the pgrowx command to work.) Btw, your recipe didn't quite work for me: the first step failed when I pressed RET "on the first line" of the buffer presented by "M-x magit-status" in the current release branch tip. It said there was nothing to show about that line. I needed to find a suitable line further down in the buffer. Am I missing something here? Can you specify precise steps, assuming I know nothing about using Magit? Thanks.
