There's an overflow bug in format_k2 in 3.5b12 that means that top can
corrupt the SIZE field of processes which allocate 2TB or more of memory; that
seems to be fixed in 3.8b1 but I've noticed that if a process allocates
over 2TB then it doesn't show up at the top of the display when sorting
by SIZE in 3.8b1; I suspect there must be another overflow somewhere.
I'm sure it'll be a good few years before anyone actually hits this
bug running real programs, but I don't know if it might affect other
