Re: Emacs carbon crash, and beginner question...

[Martin Fredriksson]

Hi again Kim,

Don't know if my gdb output was useful or if you already found the 
problem, but here is some more info.

I can now reproduce the crash.  Perhaps not the simplest way, but 
following does it.

(1) Start emacs without any init file and with set geometry (to make 
sure my example works)

    emacs -q -geometry 80x40+0+0

(2) Open text file (I enclose an example "apa.txt") marked up for 
outline and with more lines than fit in one window (scrolling is needed 
to trigger the crash).

(3) Go to end of buffer (so that text scrolls)

(4) Press C-o C-t ('hide-body').  Buffer is still "scrolled" (you don't 
see the top of the buffer).

(5) Move up two rows ('previous-line' x 2).  This scrolls down so all 
text is visible.

(6) Press C-o C-a ('show-all')

    CRASH.

Configuration information below.  This run is from Emacs/X11, same 
result for Emacs/Carbon.
