Almost all universities in the US teach in CS what is needed to know how to deal with this issue. Not many universities go from electron to semi-conductors. But you don't need that to understand overflow/underflow. For example, as an undergrad I had a year of architecture and a quarter of digital circuits. So we study how to build an 8bit CPU from the digital logic level. And then we study assembly language. Then microcode (have to implement 68K support for VM), microinstructions, controllers, DMA, RAM, ROM, registers, caches, TLBs, up the foodchain, etc... Again we don't understand this at the analog circuit level or lower, but I'm unclear at how solid state physics knowledge would help prevent this bug? If you understand what I've described, you shouldn't have any problem seeing where this issue came from.
