bus error crash in Nether

[tacotexmex]

When in Nether, the game regularly crashes with 39495 bus error. It hasn't happened at all until I started going to Nether.

This is a typical scenario:

2017-12-15 17:05:01: ACTION[Server]: texmex [127.0.0.1] joins game. 
2017-12-15 17:05:01: ACTION[Server]: texmex joins game. List of players: texmex

Does it always happen when you travel to the Nether, or do you sometimes luck out?
Does it happen immediately or with a short delay?
What happens if you try it again in other worlds?

I assume you were using Minetest 0.4.16.
What about the MineClone 2 versio you used?

Sooner or later when in Nether I'd say. Sometimes I can stay ~5 mins before it crashes. I get the feeling it happens in proximity to mobs.

Yes, MT 0.4.16 stable (macOS).

I use "Version: 0.32.0" (972c00e944e28b27dd9056ce75b58ce32236d73e)

Yeah, this is an engine bug.
I've been told by the engine developers they need a backtrace.
Do you know how to debug? Then send me a backtrace, please.

Otherwise, please join me in IRC tomorrow or later so we can hunt down this bug together.

The world where the crashes are occurring is remote and I will have access to it tomorrow monday the earliest. I'm not sure I know how to debug any more than to have run minetest from terminal and check for error logging there. Are you referring to --info or --trace flags?

[Wuzzy2]

No, I am referring to a backtrace of a debugger, like GDB.

[tacotexmex]

Not the slightest idea. Further investigation on my part will have to wait until after Christmas.
