Crash: v0.4.14 / Book / setting debug-level

[hajo]

I'm running a fresh install of Minetest 0.4.14 on windows, with minetest_game, no mods.

I got several crashes when writing to a book,
but it wasn't reproducible when running with more logging.

That is, the program simply ended, the last entry in debug.txt is

Code: Select all

2016-10-17 21:08:55: ACTION[Server]: singleplayer uses default:book_written, pointing at [node under=235,2,83 above=235,3,83]

BTW, the "How to report bugs"-post at the top of this forum said

Code: Select all

Add "debug_log_level = 4" to minetest.conf

When trying to change that from within the game, numbers are not recognized
(now using keywords instead, e.g. "info", "action", "warning" etc.).

But when this is set with an editor, at start of game the console shows the message:

Code: Select all

WARNING[Main]: Deprecated integer value; please update your configuration.

And while minetest.conf has "debug_log_level = 4",
simply selecting debug_log_level in advanced settings,
and pressing the save-button crashes the program.

Also, it would be useful to have an entry like "Program ended without error".
With that, it would be possible to see In debug.txt that a crash had happened
when that line is missing before a "Separator"-line.

Edit:
I also get crashes when crafting/moving stuff around the inventory, without errormessage:

Code: Select all

(crash, and end of logfile)

That was just a short mining-session before the crash, lasting about 20 minutes,
with about 300 "digs" and about 30 "crafts".

Questions by priority:

1) Do you have enough free RAM? (see Task-Manager)
2) Are you using a HQ texture pack? (results in high memory/RAM use)
3) Does this crash also happen with a more recent (in development) Minetest version? (Get from here)
4) Is your graphics driver installed correctly and up-to-date?

PS: The sticky "reporting bugs" thread should be updated soon. Newer Minetest versions use words instead of numbers, which increases the readability.

* there is enough free RAM - I'm monitoring CPU-usage and Memory with ProcessExplorer
* plain Minetest v0.4.14 - no mods, no textures, singleplayer.
* I can play around with the dev-version over the weekend
* I'm pretty sure graphics/drivers is not an issue - all the crashes happened
while in the inventory, or using a book.
(Currently without a 'real' graphics card, so using the onboard-graphics,
and running with low settings - without shaders, 2d-clouds, simple leaves, etc.)

Also once a crash happened right after entering the game,
without moving from home, just opening inventory, and moving stuff around.
(Maybe it happens more frequently when moving stuff with shift-click)

Yes, I also noticed some crashed in the inventory revently. It only seems to happen when moving stacks with Shift+Click. This problem is obviously caused in the engine - so, not a mod fault or anything like that.
Opened another issue for it: https://github.com/minetest/minetest/issues/4656

EDIT: Could you please upload your dump file?
