Godot version:
3.2.2 beta1

OS/device including version:
MXLinux 19 64 bits

Issue description:
The editor crashes after I change some code, rebuild the project and open a scene at the constructor of some classes.

I'll try to make an MRP as soon as I can but maybe the stack trace has a clue.

It can happen on many of my classes, I have fields of types that don't inherit from Godot.Object initialized in their declaration, but this didn't cause editor crashes so consistently before.

Here's what the console prints when the crash happens

Steps to reproduce:
I'm not sure about the exact cause of the crash, but using a sorted list with a custom comparer makes the editor crash consistently after modifying the code and building the project solution.

I've added ``` around your output, but consider using a service such as Pastebin instead in the future.

I've added the MRP, maybe @neikeq can figure it out now.

I think this no longer happens after #38141. Let's wait for the next an updated build of 3.2.2.

Here's 3.2.2 beta 2 which includes #38141, could you confirm that it fixes it? https://downloads.tuxfamily.org/godotengine/3.2.2/beta2/mono/

The mrp doesn't make the editor crash in beta 2.
