[gentoo-user] Enlightenment segfaults?

[gentoo-user] Enlightenment segfaults?

[Willie Wong]

I was away from my computer for one week, and so ran a massive update
on sunday night. After the update, on Monday morning, I woke up to
find my xsession ended with a message on the console that said
something to the effect that Enlightenment segfaulted, because some
supporting library tries to access memory that it shouldn't be
accessing. 

I dismissed it as enlightenment throwing a hissy fit. 

But the same thing happened again this morning. The problem is, I
don't quite know how to diagnose it. /var/log/Xorg.log only tells me
it caught sig 11 and will die. 

Honestly, I don't think running strace will be the best idea yet, I'd
like to save it as a last possibility, for the only reason that I
don't even know how to reproduce the crash. X was up and running
yesterday for over 14 hours, and enlightenment just crashed in the
middle of the night. 

So: what logs should I check and how should I find out what exactly
is causing the problem?

Did you try the revdep-rebuild -p to see if there are any broken
dependencies?  Did your files in /etc/conf.d get updated?  Is your session
stuff correct in /etc/rc.conf?  Any messages in the syslog or from dmesg?

Since this was a gargantuan update on my part, I, of course, ran
revdep-rebuild immediately after the emerge --update --deep world

Then I ran etc-update and checked all the files. 

I boot into console so there's hardly anything at all there in
/etc/rc.conf

no log in /var/log/everything/, nor in dmesg. Whatever it was it has
to be userland. All I know so far is from /var/log/Xorg.0.log which
tells me that X died on SEGV, and a line in the console where I
started X from that reads something like "Enlightenment caused a
seg fault". 

Right now I am running X with 
$ xinit > Xerror 2>&1 
to see if I can capture the entire stderr that was printed (some
floated off screen so the only thing I saw was effectively that
enlightenment was bad). 

Question: During the update, there were 2 or 3 packages that I wasn't
able to update due to sandbox violations. I've been intending to
check into that later on this week. Those were dependencies of
mplayer and were not, as far as I know, dependencies of enlightenment
or X. I am hoping that those aren't the packages.

Uh.. no. 

But I am curious where you got that conclusion...

Some more observations to my problem:

   1. If, after I started X, I leave it overnight in a vc, then
   nothing bad happens. 

   2. But, if I leave it overnight in the X session, something
   crashes. 

Here's what I get from logging:

Enlightenment caused Segment Violation (Segfault)

This means that Enlightenment or support library routines it calls
have accessed areas of your system's memory that they are not
allowed access to. This is most likely a bug. It is recommended to
restart now. If you wish to help fix this please compile
Enlightenment with debugging symbols in and run Enlightenment
under gdb so you can backtrace for where it died and send in a
useful bug report with backtrace information and variable
dumps etc.

I understand that this is probably not much information  about how to
solve my problem. But is there any suggestions on what I should do 
next?

The problem is that I don't even know now whether it is enlightenment
causing the segfault or not, since it appears that it happens 
after X has shutdown....

It was recently reported  in eWeek that "A senior Microsoft Corp. 
executive told a federal court last week that sharing information 
with competitors could damage national security and even threaten 
the U.S. war effort in Afghanistan. He later acknowledged that 
some Microsoft code was so flawed it could not be safely disclosed."
The Follow Up from Microsoft says "As a result of the flaws, Microsoft 
has asked the court to allow a "national security" carve-out from the 
requirement that any code or API's be made public. Microsoft has 
therefore taken the position that their code is so bad that it must
kept secret to keep people from being killed by it."

It looks like firefox is causing the problem  or perhaps one of the GTK libs
or the GTK engine itself.

The error does not appear to be enlightenment, rather enlightenment gets
caught in the middle when X is forced to die.

Perhaps you need to compile firefox rather then using the bin?

Hum, I always compile my own firefox. Firefox-bin often throw random
errors at me. Am currently running 1.0.6-r3. Well, let me test that
hypothesis. I'll see if X still crashes if I just leave it on without
firefox running.

You might be right!
  1) Firefox is one of the applications that I updated before
  starting to get this problem. And I know I have not updated Xorg or
  enlightenment (though I did update imlib2, which is why I suspected
  E to be the problem)

  2) X didn't crash when I am just running enlightenment

  3) X just crashed again, and I was running only the barebones X
  server, a rxvt terminal, and firefox. 

I'll try downgrading firefox.
