Random crashes

[SaveTheDoomer]

Here is a better save. Just push the button in front of you, then exit the door behind using the switch on the right. Then turn right and go downside. KIling the zombies with the napalm always crashes the game.

It crashes pretty often indeed. I don't know what's going on there, Graf (or maybe someone else) should take a look at this.

Tried the savegame with Win10 with latest drd team build. The game doesn't crash. At this point i think that is a linux-exclusive bug

[_mental_]

No, I reproduced this crash on Windows with debug build.

[SaveTheDoomer]

Ah, ok. This seems a nasty bug then. The good part is that it happens at the end of a cumbersome and frustrating level

[Graf Zahl]

Classic Build shit. It accessed a sprite that was already deleted but still had a stale reference.
As a result a bogus sector number ended in the clip list.

[SaveTheDoomer]

Nothing to do, it still crashes...

That's something different than the crash I got.

[SaveTheDoomer]

I don't know, it seems the same thing that i posted earlier... except that i forgot the first part and just posted the bt, sorry...

[Graf Zahl]

Yes, your two crashes are the same, but I got a different one. I think they are caused by the same thing but I cannot fix this one unless I get it reproduced on my system.

[Redneckerz]

Judging by their profile OP uses Linux.

Perhaps it was edited because i did read a Windows reference in one of the earlier posts.

I tried to upload the coredump, but i was told it's useless. At that point, i got frustrated with the whole thing and i decided to give up.

Rick Astley would tell you otherwise, so i am glad you stuck around with new info

[SaveTheDoomer]

Rick Astley would tell you otherwise, so i am glad you stuck around with new info

Unfortunately, the bug is still there...

[mjr4077au]

@SaveTheDoomer, any chance you could test this against the latest devbuild to see if its still an ongoing issue? There's been lots of changes in the last two months

https://devbuilds.drdteam.org/raze/

[SaveTheDoomer]

Sorry for the late reply, but i didn't play a lot recently Anyway, i just tried to play the mod again using the latest git, but i still get the same segfault ... i tried to ask for help on the manjaro forum too, but they said to report the bug to the devs, so i'm back to the beginning...
Anyway, you can close the topic, i think that it's probably some obscure bug related to some library, who knows... i don't think that it will ever be fixed.

Just for fun, i re-tried with 1.1.0pre-663 with lldb and got this, it is slightly different from before :
