Follow-up Comment #3, bug #40460 (project octave):

As far as I know there is nothing non-standard with my setup. It's the same as
I've always used before. I only noticed it now because with the new release
coming soon, I ran "make check" (usually I only run the tests on the function
I'm changing) and I couldn't even finish it.

The test suite runs with octave --no-rc and I can reproduce the previous
problem starting octave that way as well. Actually, looking closer at the
previous problem, I can also cause it with the following matrix multiplication
of complex matrices:


$ octave
warning: X11 DISPLAY environment variable not set
octave:1> a = rand(91) *i;
octave:2> b = rand(91) *i;
octave:3> c = a * b;
panic: Illegal instruction -- stopping myself...
Illegal instruction
