Unfortunately, I cannot reproduce the crash following your procedure.
That's understandable, as my description was flawed. Sorry. I try again.
(1) gdb ./emacs
(gdb) run -q(2) Open apa.txt, select outline minor mode (M-x outline-minor-mode) and go to end of buffer.
(3) Hide body (must be done using keys):
C-c @ C-t(4) Go up two lines (previous-line x 2)
(5) Show all (must be done using keys):
C-c @ C-aCRASH
The bt here shows that it stops right at the line calling 'find_first_unchanged_at_end_of_row'. I don't understand the #1 entry below (unless the function has been inlined?).
