Debugging a Crash

Unity Engine
1

I have a crash that only happens in the standalone build of my game. When it crashes it generates this folder with a crash.dmp, error.txt, and output_log.txt. I’m looking for ideas on how to narrow down what is causing the crash. There doesn’t appear to be the names of any functions or files that I wrote in any of the dump files, so I’m not sure where to go from here. Any help would be greatly appreciated! I can post the full dumps in this thread if you don’t want to download a random zip file. This is the spot that it actually crashes in the output log:

There is also a null reference exception earlier, but it occurred much earlier in the session, and in a different scene, so I wouldn’t think it could be the cause. Thank you!

I’m pretty sure this crash is due to running out of memory, as it only happens on my lower end computer, and it is dependent on how many models are on screen. Even if it runs out of memory though, it shouldn’t crash, so I am going to submit a bug report.

Last time I found a issue similar to that by disabling objects in the scene and making a build, and isolating the issue. Was a particle system going wild only on build. Not developer build. 6 hours to isolate that.

Ouch. Luckily there aren’t too many things in the scene for me to isolate. I just have a ton of stars (they use particle effects as well). It is a bit of an edge case in my game, so I don’t mind if the game doesn’t work perfectly with hundreds of stars on screen, I just don’t want it to crash.
