[solved] Illegal instruction (core dumped)

I am trying out different web browsers. I installed Chromium (51.0.2704.79-1) and Opera (37.0.2178.54-1). But when I tried to start them from the console, all I got was a message: Illegal instruction (core dumped). I use rclone (1.29-1) to sync with Dropbox. It worked fine, but since a few weeks ago I get the same message. What does this message mean? What can I do about it? Journalctl gives me:

systemd-coredump[11779]: Process 11777 (rclone) of user 1000 dumped core.

Re: [solved] Illegal instruction (core dumped)

Please edit your post to add code tags - you've previously been informed about their use.

Can you post the output of the following:

grep Architecture /etc/pacman.conf
uname -a
cat /proc/cpuinfo

Have you applied any relevant microcode updates?

The microcode updates for my AMD processor should be applied via linux-firmware. I update my system weekly.

Re: [solved] Illegal instruction (core dumped)

I installed Arch Linux on my second hard drive. When I start rclone, Opera and Chromium I get the same message: Illegal instruction (core dumped).
I assumed that according to the wiki the microcode updates for my AMD processor should be applied via linux-firmware. But dmesg tells me that my AMD processor is not supported:

dmesg | grep microcode
[    1.083185] microcode: AMD CPU family 0x6 not supported

Could this be why I get those illegal instruction messages? Why do these messages not show up whenever I start any other application?

Re: [solved] Illegal instruction (core dumped)

At least Chromium needs SSE2 to run (which your processor does not support):

https://groups.google.com/a/chromium.or … O4NM69utVo
https://groups.google.com/a/chromium.or … 1E391CFJf0

Chances are that Opera is the same. However, rclone using SSE2 is probably a packaging issue (see also https://github.com/ncw/rclone/issues/437), and should be fixable in Arch.

Re: [solved] Illegal instruction (core dumped)

Thank you, pypi.

As you suspected Opera needs SSE2 to run.
