You're looking at a bunch of irrelevant information.

You have nasal demons. That they happen to occur when you do matrix
multiplication just means that your nasal demons are deep in the
system.

The only useful information here is that you're getting SIGILL. Your
Octave binaries or the libraries it depends on are seriously messed
up. Trying to diagnose it by multiplying matrices or doing other
operations is not fruitful.

When you first reported this bug, you didn't use Debian's reportbug
command. This command includes a lot of useful information, such as
which libraries you've installed and how. Is there something here that
you aren't telling us? Have you been touching files under /usr without
going though apt or dpkg? Can you run reportbug and just forward us
the form email it creates for you?

Thanks,
