Can confirm something is messed up here.

Do you realize how much of numeric error you are generating with those “transformations”? 2^24 is 1,6*10^7, i.e. beyond the 6 or 7 digit of precision “reasonably” guaranteed by float numbers (you actually have even less if you chain too much operations).
Seriously… Please keep a minimum of common sense and do not try insane things to make Blender crash. Or at least, do not report this as a bug!

Think its fine to report bugs like this, sometimes they expose weakness in the algorithm - or are some extreme case that could still occur in more typical cases.
However its not always reasonable for us to spend many hours investigating a fix for issues which are a real corner cases and not something you would generally do in practice.
Blender shouldn't crash even if some object is far from its origin of course, I looked into the crash and its not some simple fix (float out of int range or skip NULL pointer access).
