It's happening somewhere inside test/turing/compiler.jl.

I've not (yet) been able to figure out where this is happening. However, my experience is that bugs disappear when I try to investigate them, so my first step will be to declare that I'm investigating it.

If that doesn't work, subsequent steps would be to figure out exactly which function call causes it to OOM and maybe try inserting a manual garbage collection call before that.

I have seen this error a few times in the past. It is due to a memory constraint of CI virtual machines and likely has nothing to do with Turing.

This is still frustrating. Someone needs to figure it out imo

Even after removing the offending test/turing/compiler.jl file, it's now happening in doctests as well
