This is not crashing, but giving very strange answers. It is very difficult to set up the example calculation -- you need many layers of scientific software (R, ADMB) plus a bunch of compiler and dev software. And, it seems, just the right WiFi network. Still, I had an Asus Eee 1005HA with a bad processor that was very difficult to make go wrong except in large data transfers. I'm inclined toward a h/w issue myself, but it is conceivable that a driver in the right circumstances could corrupt memory where numbers are stored. And the ADMB s/w uses lots and lots of GB and ends up swapping sometimes.
