No, actually every bug is a logical consequence of the overall code used for the software and its environment (and their compilers), and what software does is well-defined. It just appears weird to us since humans are so limited in their ability to think. I mentioned something like that in
#331.
So, in essentially the same system, the same software cannot behave differently. So somehow, our systems / environments must be different. It is just weird,
how different:
If the behavior of the same software is being
consistently different on two system, things must be very weird. In fact, I think it is much more likely that you made a mistake or are not telling the truth.
