Looks like the answer is 0.

What you say about mixture models is true in general, however this fit was

I'm sorry, but I will most likely withdraw R.huge from CRAN anytime

So S is numerically singular: the last 10 or 11 values are effectively 0.
As Peter Dalgaard said, scaling may help but only if the parameters are on
drastically different scales.
