gzdoom-g1.8.1-303-gcb74dd9 crash

[Ed the Bat]

This build of GZDoom crashes to desktop (with no fatal error) when trying to run certain maps. This mapset provides a fine example.

I have been unable to determine the cause of the crash, but deleting all 3D floors, all slope aligns, all polyobjects, and the skybox camera seems to stop the crash. I'm in over my head with this one.

The previous build, gzdoom-g1.8.1-285-g834678a, did not crash like this, nor does any version of ZDoom I've tried.

Interesting. From the timing of the crash (on exit) I would have guessed that it was the same as this. However, there are no models in this example and models seem to be responsible for the crash in that thread.

That being said, I have just tried clavnoxr three times and not got the crash.

That worries me greatly. Could the issue be specific to my hardware? I'm finding it with other map packs, too. Ones that use complex architecture like 3D floors and skyboxes, which means I'm not really any closer to isolating the issue than I was before.

I don't suppose GZDoom does something cunning like effectively convert 3D floors to models on the fly or something does it?

[Ed the Bat]

I should mention that I did try some simple experiments with a small map that has a 3D floor in it, and tried changing a few things here and there to see if I could isolate a cause. With a basic 3D floor, even when swimmable, using a warping texture (which I was suspicious of since those got tweaked recently), I couldn't cause a crash. Of course, mapping is not in my main skillset, so I could've missed something, or it may be more closely tied to things I have no experience with, like slopes.

But, if this all does turn out to be a conflict with my hardware, I suppose that would be one more push for me to start shopping for a new machine.

Why should it?

[Enjay]

I guess that it shouldn't.

[Graf Zahl]

No, and the model crash is fixed now.

I just tried gzdoom-G1.9pre-312-gb6dab83, and the crashes have stopped.

I'd be interested if you had time to poke around and push this a bit further to see if any of the mods that you were having problems with still cause a crash/ I'm still getting a crash on exit but I don't have the opportunity to look at it any further for a few days.

Using gzdoom-G1.9pre-312-gb6dab83, Clavicula Nox no longer crashes at map launch, nor does it crash on exit. Same for Braham Manor (it's for Vavoom, so I rewrote the models from xml to MODELDEF so it'll work correctly in GZDoom); no crashes.

I do, however, experience a crash on exit (report attached below) when playing Dawn of Reality, but considering it's a gigantic map, the sheer size of it may be more to blame than anything...

Ah, thank you. I too get a crash with DoR and have uploaded a crash report and (possibly meaningless - because I don't really know what I'm doing ) minidump result screenshot to the above linked GZDoom thread. If I have done the minidump thing correctly, it's interesting that it points to a similar line but in a different file to the minidump screenshot that I already posted in that thread.

Anyway, that's me out for a few days now.

Fixed the DOR crash. It was also model related but something different. This time it was trying to delete the skin textures twice.

[Enjay]

I've only had a chance to make a very quick check because I'm about to head off for a few hundred miles drive but, so far so good with both DoR and my own mod.

I've put a build on line over at the DRD development builds site too.

Thanks for the fix.

I wonder if any of these recent model fixes would have any effect on the model brightmap hack that was recently discovered?
