Well, it is exactly 2 variants of 1, 2, 3, 4 each.  I suspect that the
order of grob evaluation at some point when a system is printed depends
on the order of memory addresses.

Find that point and you'll likely also have the culprit for various
other stuff behaving non-deterministically, like what is drawn on top of
what and other things frequently turning up in "make check".
