Segmentation fault (core dumped) in few applications

squer · 2016-09-18 20:21:14

Hello, I was searching for issue, but i didn't found anything.
For example

Pidgin:
$ pidgin
Pidgin 2.11.0 has segfaulted and attempted to dump a core file.
This is a bug in the software and has happened through
no fault of your own.

If you can reproduce the crash, please notify the developers
by reporting a bug at:
http://developer.pidgin.im/simpleticket/

Please make sure to specify what you were doing at the time
and post the backtrace from the core file. If you do not know
how to get the backtrace, please read the instructions at
http://developer.pidgin.im/wiki/GetABacktrace
Aborted (core dumped)

leafpad:
$ leafpad
Segmentation fault (core dumped)

Any ideas? It started after reinstalling arch I don't know what to do, laptop with the same configuration is working

edit, lxrandr too

$ lxappearance
Segmentation fault (core dumped)

Do you have an Intel CPU? Have you enabled microcode updates?

Mod note: not a Sys Admin problem, moving to NC.

yes, installed intel-ucode and updated grub by # grub-mkconfig -o /boot/grub/grub.cfg

Check that it's actually applying.

dmesg | grep microcode

If everything looks good, tell us more about the crashes.

dmesg looks bad:

$ dmesg | grep microcode

intel says that i5-2500k have it, wth

checked in grub.cfg
" echo 'Loading initial ramdisk ...'
initrd /boot/intel-ucode.img /boot/initramfs-linux.img"
is already, try reboot one more time

I rebooted and found that issue

Do you have any other copies of grub on your system that might be used instead of the one installed on Arch?

Check the contents of /proc/cmdline, on systemd-boot at least it lists the initrds that were loaded, I imagine grub does the same.

systemd-modules-load failing is unlikely to be related to your segfaults. However, please post the output of

systemctl status systemd-modules-load.service

along with the previously requested coredumpctl information.

is not enable your microcode,

I'm getting the exact same error (also a seg fault when starting Pidgin)

does anyone know the reason for this segfault?
it worked a couple of days ago just fine....

micsnare · 2016-09-28 20:01:38

finch (text-based pidgin) seems to work, so it seems to be something GUI-related.....
