James,
I had a similar "cmae" crash (although it may have had a different cause). One of the things I changed is that I made sure the optimizer could not somehow be activated outside of an optimization run, i.e. I used my code also to plot/explore/etc. So I use the following code which, in my case, seems to have stopped the crash from happening:
WhichOptimizer = ParamList("Which Optimizer?", ",spso,trib,cmae");// Leave the comma before spso !!!
your code
if (WhichOptimizer != "") OptimizerSetEngine(WhichOptimizer);
Obviously you can further "protect" this by stating something like
if (Status("action") == 5) if (WhichOptimizer != "") OptimizerSetEngine(WhichOptimizer);
It may also help in your case.

Even stranger the first time I ran the file today it took 5.5 minutes to run the 61 steps, and now I just ran it in 42 seconds. I don't understand it.
