Memory allocation crash

I'm getting a memory allocation crash every now and then with my iOS build. Now using 2018.1f2 but this happened earlier as well. Usually making a new build fixes the issue so it's not really related to our app. And we don't allocate memory like this, that's 28 GB. Anybody seen something similar?
