The bug
The server crashes upon replacing soul sand with a magma block or replacing a magma block with soul sand under a tall bubble column (tested with 2032 block tall water).
Discovered while testing the fix of MC-214082.
A crash report is attached, as well as the world generation settings file used to create the world.
How to reproduce

Select Singleplayer → Create New World
Set your Game Mode to Creative, and make sure cheats are allowed

file

I was able to reproduce this. It appears that the stack trace in the crash report is different each time I reproduce this. Also, once I tried using a launcher profile that gave Minecraft 4 GB of RAM instead of the default 2 GB, but it still crashed. Here is one of the crash reports:
I personally couldn't reproduce but since it's a stack overflow, that could be expected.
