Mono version crashes on build (Ubuntu 21.04) #49071

Open Teonyr opened 3 years ago

Teonyr commented 3 years ago

Hey, I already searched open and closed issues but couldn't find something related to my problem. Mostly people had MSBuild missing or something. I have dotnet-sdk-3.1 (as well as 5.0) and mono-devel installed. Editor and project are setup to use visual studio code as external editor and MSBuild for building solution.

Godot version: v3.3.2.stable.mono.official

OS/device including version: OS: Ubuntu 21.04 x86_64 Kernel: 5.11.0-17-generic CPU: AMD Ryzen 7 3700X (16) @ 3.600G GPU: NVIDIA GeForce RTX 3080 Memory: 3035MiB / 32088MiB

Issue description: Mostly after editing a C# file, the editor crashes when rebuilding the solution. But this doesn't happen all the time. Sometimes (2/10) it won't crash.

Here is a --verbose output on pastebin: https://pastebin.com/rkA4u31W

Steps to reproduce: A:

  1. Open project
  2. Click on MSBuild
  3. Click >Build
  4. Click Rebuild

or

B:

  1. Open project
  2. Edit .cs file
  3. Click Play (>) or Build

Minimal reproduction project: MonoCrashRepro.zip

I'm experiencing this same crashes with dotnet CLI as build tool. (and have since 3.2)


OS: Arch Linux x86_64
Kernel: 5.12.3-zen1-1-zen
CPU: AMD Ryzen 5 3600XT (12) @ 3.793GHz
GPU: AMD ATI Radeon RX 590 (Mesa 21.1.1-1)
Memory: 13102MiB / 16005MiB

Here's a back-trace of a crash, hope it's useful.

I have also been experiencing this on 3.3.2 Mono. Yesterday I had probably 10+ crashes over the span of 4 hours. Very frustrating. I don't recall having any crashing issues until I updated to 3.3, but I see others have had it since earlier.

Using MSBuild on Windows 10 Pro.

Edit: I should probably also add that in my case it doesn't seem to happen nearly as frequently as it does for @Teonyr. For me the crashes happen probably more like 1 in every 10-15 builds, but when you're deep into debugging something you can go through 10+ builds very quickly which still results in being a major annoyance.

This is the error from OP's log:

Mono: Loading assembly GodotTools.ProjectEditor... 

ERROR: load: Loaded assembly missing from table. Did we not receive the load hook?

Can every one else reproducing this see the same error?

Keelar commented 3 years ago

Okay so I tried to reproduce it again to get the error and it does appear to be different in my case. The description of this issued just sounded identical to mine so I just assumed they were the same. For me it seems to be just the editor that crashes and I get absolutely zero errors in the console even when using --verbose. But the crash only happens while building. Do editor errors not print to the console? I also tried digging through the logs in AppData\Roaming\Godot to see if an error showed up in any of those and can't find anything whatsoever.

If this is indeed different I'll have to submit another issue but I'd like to actually find the error to report to make sure it's different.

My logs do not seem to contain such error.

Also, I've noticed that I am not able to reproduce this issue in 2D scenes.

valters-tomsons commented 2 years ago

Issue still reproducible in Godot 3.4 and 3.4.1-RC3

brmassa commented 2 years ago

Same here using 3.5.beta1, dotnet 5 and building using dotnet cli option

Pressing build or play is a Russian roulette.

Impractical to create a big project using C# because the editor crashes every 10min. Today only was 20+ crashes.

The crash reports files "mono_crash.0.XX.json" always point to "crashed" : true, in"thread_name" : "Godot".

valters-tomsons commented 2 years ago

If anybody is interested, 4.0-mono builds do not seem to suffer from this issue.
