[SOLVED] Segmentation faults

Laurent · 2009-02-09 19:40:38

Hi people!

I'm configuring Arch after I installed it, but that's not my main problem.
I'm experiencing segmentation faults.
Yesterday I updated my system, just after I installed it, with pacman -Syu;
I'm installing ALSA like the wiki tells me. But when I ran alsamixer I get a segmentation fault.
So I thought, bad luck, maybe it's just ALSA and I installed something very mainstream: Lynx, but when I ran lynx I got a segmentation fault too!
How is it possible that everything I install gives segmentation faults? My RAM is not broken because I can use livecd's who are fully using my RAM with no problem;
Is it a userrightsproblem? And how to fix it?

What type of system do you have? (PII, P4, AMD, etc...)
Does dmesg show anything?
Is your cpu over clocked at all?
Maybe your hard drive is bad?

On top of what pyther asked, you may also want to try a stace trace or gdb to see if the segfaults are happening in the same library.

Laurent · 2009-02-09 21:39:40

I have an AMD Athlon 64 3000+, never clocked it in any way
I don't think my hard drive is bad, I have two hard drives in raid1, one is about 5 years old, the other is 1 month old....

dmesg showed indeed something but I didn't understand a thing of it. (I'll search for it, I must reboot, my livecd won't mount them)

It's also strange that only programs installed after my system was installed (and thus after pacman -Syu) show segfaults.
Should I roll back my pacman? Maybe my kernel compiled not that right. I read something on the internet about a bad glibc, is that possible?

Sorry I'm a bit n00by, but I never experienced segfaults before

skottish · 2009-02-09 21:44:50

glibc was one of the libraries that I was thinking that gdb may expose. You can still run pacman right? If so, try and force reinstall glib with pacman -Sf glibc.

Sorry, it was not in dmesg.log but in messages.log I saw an error.
When I ran lynx I got a segmentation fault which messages.log confirmed

Feb 9 22:45:03 apollo lynx[3362]: segfault at 400000 ip 7f46eb456f48 libc-2.8.so[7f46eb3f2000+14a000+]

So libc is the evil. I'll try to reinstall it tomorow, it's to late now.... *need sleep*
Thanks for the help

A last question: Why can't fstab mount partitions with an ' in the name (e.g. /home/laurent/Afbeeldingen/Foto's), even when I escape them with a backslash?

EDIT: lots of typo's discovered, it's late, yes

Try using quotes instead.

Laurent · 2009-02-10 19:01:24

The fstab solution was just using the ascii codes for a single quote (\047).

(g)libc is still the evil. Now it is version 2.9 instead of version 2.8 after a pacman update.
And pacman -Sf glibc gives no difference, I still get segmentation faults.
How is that possible?

skottish · 2009-02-10 19:13:18

You're segfault posted above was for glibc-2.8, and as you pointed out Arch is at 2.9 now. Is your system fully up to date as of today?

Laurent · 2009-02-10 20:05:54

Fully up to date, yesterday it was fully up to date too!
It seems strange to me

EDIt: Solved!
I saw that the Belgium mirror was three days out of sync, so I switched to the French mirrors and ran a pacman -Syu, now, everything is just fine

Thanks. I'm suffering from pre-caffeine syndrome. I'm getting better now.
