Indeed it is rather amusing to think of an example with very large
text size. First I thought it's very hard. But let me see.
Suppose you have a rather complicated function of 50 variables
which takes about 500kB. Then full second derivatives (say,
using Maple or 2500 people) will take about 500kB x 50^2 = 1 GB.
(think of dynamics calculation or just very complicated
formulae which predict that something very important happens)
People routinely generate portions of their code using algebraic
manipulators. My personal experience is rather modest - a few tens
of kilobytes with dimensions less than 10.
Sure, this is pretty close to program generating a program.
But overbloated code size is exactly what you end up with.
So I would not be too surprised to learn that somebody has already
beaten the 32 bit text limit.
