Package: xterm
Version: 4.3.0.dfsg.1-4

xterm crashes with segmentation fault when i middle click or press
shift+insert inside xterm. gnome-terminal doesn't crash.

It seems xterm started to crash after I upgraded it to 4.3.0.dfsg.1-4
version today.

Is this the same as 250655 ?

No, since in my case problem is not specific to AbiWord. Xterm always
crashes when I try to paste into xterm window, no matter which app has
the selection.

#250655 says xterm crashes with AbiWord only if I understand it
correctly.

I think it's a little more general than that. The AbiWord case breaks
when one pastes UTF-8 text into xterm, and seems to be a bug in the X
libraries.

Interesting.

Could you repeat this process with the following modifications?

1) Install the debugging versions of the X libraries xterm uses.

Since xterm depends on: xlibs-data, libc6 (>=3D 2.3.2.ds1-4), libexpat1 (>=
=3D
1.95.6), libfontconfig1 (>=3D 2.2.1), libfreetype6 (>=3D 2.1.5-1), libice6 |
xlibs (>> 4.1.0), libncurses5 (>=3D 5.4-1), libsm6 | xlibs (>> 4.1.0),
libxaw7 (>> 4.1.0), libxext6 | xlibs (>> 4.1.0), libxft2 (>> 2.1.1),
libxmu6 | xlibs (>> 4.1.0), libxpm4 | xlibs (>> 4.1.0), libxrender1, libxt6
| xlibs (>> 4.1.0)

=2E..this would be:
libice6-dbg libsm6-dbg libxaw7-dbg libxext6-dbg libxmu6-dbg libxpm4-dbg
libxrender1-dbg libxt6-dbg

2) Run xterm with LD_LIBRARY_PATH in the environment. You may have to run
xterm as root for this to work, as I think observance of this variable
might be suppressed for setuid and setgid programs (xterm is setgid utmp).

3) Use "bt full" instead of just "bt".

This might be enough information for us to figure out where to look in the
libraries for this problem.

Thank you *very* much for your followup and assistance!

I think I have problems running xterm with debug libraries linked. I
have no experience with C debugging, so I might be doing something
wrong.

I've installed debug packages you provided and have now a bunch of .so
files in /usr/X11R6/lib/debug

I'm trying to run xterm this way:

  root@kedjob:~:)$ LD_LIBRARY_PATH=/usr/X11R6/lib/debug/ gdb xterm

However after I run program in gdb prompt I see lots of the same "(no
debugging symbols found)..." messages and backtrace is the same as in my
previous post (i.e. without most of debugging symbols).

So I guess there is something wrong in my procedure... Could you please
help me with that?

You'll still get a few, as xterm links against some libraries that aren't X
libraries, and won't have debugging symbols.

Well, could you try just getting a core dump from xterm first?

Thanks, Thomas!

Reassigning and updating this bug accordingly.

Bug submitters: assuming our diagnosis is correct, you can expect this bug
to be fixed in the next Debian package release of XFree86.

This was already filed as #250655. If it had not already been filed,
however, your report would not have included enough information for us to
handle it well.

[The following is a form letter.]

Hello,

You recently filed a duplicate bug report against a Debian package; that
is, the problem had already been reported.

While there is often nothing inherently wrong with doing so, the filing of
duplicate reports can cause Debian package maintainers to spend time
performing triage and maintenance operations on bug reports (e.g.,
instructing the Debian Bug Tracking System to merge the duplicates) that
could otherwise be spent resolving problems and doing other work on the
package.

One very good way to file bugs with the Debian Bug Tracking System is to
use the "reportbug" package and command of the same name. A very nice
feature of reportbug is that, if the machine where you run it has network
access to the World Wide Web, it can query the Debian Bug Tracking System
and show you existing reports. This reduces the chance that you'll file a
duplicate report, and offers you the option of adding follow-up information
to an existing bug report. This is especially valuable if you have unique
information to add to an existing report, because this way information
relevant to the problem is gathered together in one place as opposed to
being scattered among multiple, duplicate bug reports where some facts may
be overlooked by the package maintainers. The reportbug program also does
a lot of automatic information-gathering that helps package maintainers to
understand your system configuration, and also ensures that your message to
the Debian Bug Tracking System is well-formed so that it is processed
correctly by the automated tools that manage the reports. (If you've ever
gotten a "bounce" message from the Debian Bug Tracking System that tells
you your message couldn't be processed, you might appreciate this latter
feature.)

Therefore, I strongly urge you to give "reportbug" a try as your primary
bug reporting tool for the Debian System. (If you already do use
"reportbug", please see below.)

One way to install reportbug is with "apt-get"; for
example:

  # apt-get install reportbug

The "reportbug" command has a few different modes that cater to different
levels of user expertise. If this message has contained a lot of jargon
that is unfamiliar to you, you likely want to use reportbug's "novice"
mode; here's one way to do that.

  $ reportbug --mo...
