Well, from the little information we have, I suppose we can only 
be reading too much in it.

So, I like too to think it's just due to an integer overflow. But 
not from a software engineer perspective, but more from a Marxist 
approach. One misses a simple test over an integer, and you make 
a rocket-ship worth billions of good money (that could be used in 
education, medical care or whatever) explode in tiny cold little 
pieces, 54 millions km from here.

What an ironic and subversive bug, the engineer who did that 
should be immensely proud of himself. :)
