I did some testing on this issue, this is what I have found out:
The closest I was able to get the issue to start happening was after I passed the X coordinate of 8.388.455. Thus, the closest chunk I crashed on was at "524290,10". Which is close to 524288. Isn't 524288 = 512 Kib? Maybe that's a valuable clue?
The crashes happen even on a world generated on 1.13-pre8.
The issue is present in the latest version of Java 8, and also Java 10.
Basically, to recreate the issue yourself:
Create a new world (in 1.13-pre8, ofc)
/tp @s 8388455 ~ ~
Start moving towards positive X. You should crash in around a minute of travelling, probably depending on your render distance.
EDIT: Collected some more info:
The crashes occur only when at least one of the coordinates exceeds the value above. If you travel the same amount of blocks diagonally (eg. to X: 5.000.000 | Z: 5.000.000), crashes do not occur.
When done on the same world seed, it will always be the same chunks that cause the crash.
Structure generating set to "off" does not seem to make the difference.
