bug#716: 23.0.60; opening tgz file causes emacs crash

bug#716: 23.0.60; opening tgz file causes emacs crash

[robert marshall]

If I open a tgz (tar and gzipped file) in emacs it immediately crashes 
(giving the windows emacs abort dialog)

The file I used to test this was
http://download.savannah.gnu.org/releases/viewmail/vm-8.0.11-581.tgz
but the problem seemed to occur for other tgz files

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
c:/tmp/emacs/etc/DEBUG for instructions.

In trying to debug this, I think I have found where it is going wrong, 
but I have no idea why and how to debug the relevant bytecode. It could 
be a sign of the byte compilation going wrong on Windows (line-end or 
other coding problems?), or a bug in Fbytecode somewhere (which is only 
affecting Windows for some reason). The stack trace when debugging 
includes the following:

#8  0x010a5e65 in Finsert (nargs=2, args=0x0) at editfns.c:2224
#9  0x0115795b in Fbyte_code (bytestr=48986435, vector=49414916, 
maxdepth=48)
    at bytecode.c:1265
#10 0x01023232 in funcall_lambda (fun=49839780, nargs=0, 
arg_vector=0x82d854)
    at eval.c:3229
#11 0x01022d11 in Ffuncall (nargs=1, args=0x82d850) at eval.c:3088

In frame #11, args[0] is tar-summarize-buffer, so at that point all 
appears normal.
By frame #8 things have clearly gone wrong. How did args become a NULL 
pointer, yet there are 2 args?

Currently I don't have access to a GNU/Linux machine to try a copy of 
tar-mode.elc compiled there. Can someone else with access to both 
platforms try that? To reproduce the bug, you need to open a tar file in 
Emacs (trunk) maybe a few times (the most I have had to open one before 
triggering the bug is 3 times, but often it happens first time).

On further investigation, I think I was seeing symptoms of the problem 
(smashed stack), not the cause. The NULL argument I observed was 
inconsistent with the next stack frame up, where the same argument was 
perfectly valid.

The problem starts to occur with version 1.126 of lisp/tar-mode.el. This 
version contained a rewrite to use separate unibyte and multibyte 
buffers rather than switching between them in the same buffer. I think 
something is going wrong here - a possible problems is that the buffer 
where the crash occurs has a buffer-file-coding-system of 
iso-latin-1-dos, but my tar program outputs unix line ends (checked by 
redirecting output to a file, and letting Emacs auto-detect line ends in 
that file).

bug#716: Bug in buffer-swap-text (was Re: bug#716: 23.0.60; opening tgz file causes emacs crash)

[Jason Rumney]

I've managed to reduce this to a small test case that shows that the bug 
is in new function buffer-swap-text.

Create the following new buffers:

---- test1.txt ----
This is buffer 1
(buffer-swap-text "test2.txt")

---- test2.txt ----
This is buffer 2
(buffer-swap-text "test2.txt")

After creating these buffers, switch to test1.txt buffer and press C-x 
C-e at the end of the second line.
This works fine, and you can swap the two buffers without problem 
repeatedly.

Now, still in test1.txt buffer, C-x RET f binary

Now try C-x C-e on the second line again. Perhaps not on the first try, 
but sooner or later Emacs crashes.

Should be (buffer-swap-text (get-buffer "test2.txt"))

I've also found that the crash only happens if buffer-swap-text is 
called from the binary buffer, and only if the other buffer is not binary.

I cannot reproduce this bug with your test case; however, the crash
opening .tar.gz files is still there.

bug#899: 23.0.60; Opening a foo.tar.gz file crashes

[Yary Hluchan]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Create a couple small text files- in my case sample1.txt containing:
Here is a sample. Hello!
and sample2.txt containing:
foo bar bat baz

put them in an archive with:
tar -czf sample.tar.gz sample?.txt

Then open a fresh instance of emacs, C-x C-f sample.tar.gz and it crashes.

I don't have gdb installed, but I can give you a link to sample.tar.gz
http://www.driveway.com/r4h5t5i7r1
My other tar.gz archives also crash emacs.

bug#1088: 23.0.60; Crash during opening a large .tar.gz file

[TAKAHASHI Yoshio]

Emacs crashes when I try to open a large .tar.gz file, in this case it's
`w3m-0.5.2.tar.gz'.  Emacs crashes during opening a large zip file, too.

I use today's cvs head, on below platform:
* Windows XP Professional Ver 5.1 Build 2600 Service Pack 3
* build by cygwin/gcc3 "-gdwarf-2 -g3 -mno-cygwin -mtune=pentium4 -O2"

Below is the output from `bt full' and `xbacktrace'.

Subject: 23.0.60; Crash during opening a large .tar.gz file
Date: Sun, 05 Oct 2008 13:37:45 +0900
Message-ID: <7zzlljzmg6.fsf@yfb02119.nifty.com>

Emacs crashes when I try to open a large .tar.gz file, in this case it's
`w3m-0.5.2.tar.gz'.  Emacs crashes during opening a large zip file, too.

I use today's cvs head, on below platform:
* Windows XP Professional Ver 5.1 Build 2600 Service Pack 3
* build by cygwin/gcc3 "-gdwarf-2 -g3 -mno-cygwin -mtune=pentium4 -O2"

Below is the output from `bt full' and `xbacktrace'.

Initial report:

    Steps to reproduce:
    1. Create a small tar file with 2 or 3 files in it
    2. emacs -q
    3. M-x load-library tar-mode
    4. Open the tar file
    You see the crash (with earlier posted stack trace)

    I saw another crash with the following steps:
    1. Repeat #1, #2 from the previous scenario
    2. Open the tar file, you will see the file listing
    3. Position the cursor on one of the listed files and hit enter (open
    the file in the archive)
    You see a crash. Stack trace follows for 2nd scenario:
