Follow-up Comment #1, bug #35021 (project octave):

Just as an experiment, I did (X+1)'*X and it did not core dump. 

Here are the results of the experiment:
octave:1> load coredump.mat
octave:2> (X+1)'*X;
octave:3> X=X+2;
octave:4> X'*X;
panic: Floating point exception -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Floating point exception (core dumped)
