Possible memory corruption when running LINMOD

All,

Attached is a .zip with a simple script and model that illustrates a possible memory corruption problem that I've run into in a larger system (NOTE: the .slx is saved in R2015b).

1. Open both the .m and .slx
2. run 'testSim_INIT.m' as is
3. If you see some diverging signals on the scope then the simulation successfully ran
4. Go to the last code section on 'testSim_INIT.m' and run just that section (click in section and CTRL+ENTER)

You should get the following error,

Expected an integer value, found an non-integer variable  with value 1e-05 .

MATLAB Function 'MATLAB Function':     var(:,i) = rand(6)*var(:,list(i)); 
                                                                ^^^^^^^

Now, open the matlab function 'myTest' on the block diagram of 'testSim.slx'. Comment out the line,

list = model.list;

and uncomment the line,

list = (0:4);

Now, rerun steps 1-4. Notice that LINMOD now runs w/o error.

You can repeat these tests after toggling the manual switch on the block diagram to route 'In1' to the 'myTest' instead of the constant.

QUESTION/CONCLUSION:

It seems to me they there is a memory corruption as the error claims have received a non-integer value out of 'list(i)'. I have seen the exact same results in R2015a, R2015b and R2016b.

Am I simply missing something obvious?
