Thanks!

What I did was create a 3x3 matrix as in:
m:=[[1 2 3][4 5 6][7 8 9]];
....just use the matrix editor and you can make it.

Then when you type m, you should get:
m = 1 2 3
4 5 6
7 8 9

Next, execute the following command...make sure you are in CAS mode first...

m[4]=<99; // This is actually array_sto(99,at(m,3));

This will create m = [[1 2 3][4 5 6][7 8 9]99]
...which is a malformed matrix

You can go to shift-matrix
scroll to m[CAS] and click on it.
It will cause the reboot.

I'm not too worried about it at this point. Clearly I did an illegal operation. I was assigning a scalar to a matrix row for which space was not yet created.....so it's an illegal access, which is causing a reboot.
