I got this today (I was running without --enable-checking until today).

I still have that session open in case you want more info.

Also, as a side note, in the current buffer (in which I'm reporting the
bug), I see problems like <end> going five to 5 to 10 lines below
current position. Apparently, it happens after I use C-k (kill-line). It
goes way when setting (setq cache-long-line-scans nil). I guess the
crash and this problem are related ? If not, I can make a separate bug report.

I'm running emacs-24 branch at commit
ef5b917 * savannah/emacs-24 Fix relative links to parent directories in shr
*but* I also have applied Paul Eggert's patch mentionned in bug#17172

It's related, but can you reproduce this in "emacs -Q"?

Not sure what this means, Paul made several commits during the last 2
days.  Can you be more specific (or even state the bzr revision
number)?

What is the value of BUF_Z(b) in frame #2?

Also, what is the major mode in the buffer in question?

Not yet, but it seems to be triggered by the bug report because it just happened again. I'll look at it later. I have to run now.

From the comment you left there, I guess you found it. I'm referring to http://permalink.gmane.org/gmane.emacs.bugs/88024.

Perhaps I'm using the wrong command ?

Could you tell me how to find out with gdb ?

No, you just don't need xpr, 14231 is a simple number.

(gdb) p b->name_
(gdb) xstring

This will print the name of the buffer, which should be enough for you
to know its major mode.

Indeed

(gdb) p b->name_
$5 = 155534625
(gdb) xstring
$6 = (struct Lisp_String *) 0x9454520
"#emacs@irc.freenode.net"

It's rcirc-mode.

I finally managed to make a recipe that reproduces the crash every time
for me (slight variations of it will reproduce the erratic end-of-line
problem)

gdb --args emacs -Q -nw /home/youngfrog/emacstest2.txt  --eval '(execute-kbd-macro (kbd "C-e C-n C-e C-n C-e C-n C-e M-< M-f C-k C-n C-n C-e"))'
(gdb) r

The crash is the same as reported.

emacstest2.txt is the file attached.

[-- Attachment #2: emacstest2.txt --]
[-- Type: text/plain, Size: 132 bytes --]

qfoo bar baz

Breakpoint 1, terminate_due_to_signal (sig=6, backtrace_limit=2147483647) at emacs.c:351
351	  signal (sig, SIG_DFL);

[-- Attachment #3: Type: text/plain, Size: 97 bytes --]


This time the buffer b is in text-mode (it's the buffer which visits emacstest2.txt)

Thanks, I reproduced this, and will look into it in a couple of days,
if no one beats me to it.

> The crash is the same as reported.

Not exactly: it hits assertion violation on this line:

		start_byte = CHAR_TO_BYTE (start);

whereas your original report did that here:

            ceiling_byte = min (CHAR_TO_BYTE (next_change) - 1, ceiling_byte);

But it's probably the same problem, so this recipe should be good
enough for starters.

Hm, I can't reproduce with this recipe (as of bzr revision 116978).

There's no such revision on the emacs-24 branch.

Please try the latest emacs-24 branch, I committed a change that fixes
the above recipe, but I'd like to know if your original use case is
fixed as well.

Thanks.
