Several physics related crashes when running test project #47440

Open qarmin opened 3 years ago

qarmin commented 3 years ago

Godot version: 3.3.rc.custom_build. ed1f5c29b

OS Ubuntu 20.04 - Ubuntu 3.36 X11

Issue description: Running my new physics test project crashes Godot with very different backtraces. Some of crashes was reported in e.g. #47438, but since I have seen a lot of different backtraces, I'm not sure if they are releated and it is very hard to create minimal project, so I'm posting here full project.

If needed, I will create 4.0 version of this project

Example asan report with backtrace:

ERROR: get: FATAL: Index p_index = 0 is out of bounds (size() = 0).
   At: ./core/cowdata.h:156.
handle_crash: Program crashed with signal 4
Dumping the backtrace. Please include this when reporting the bug on https://github.com/godotengine/godot/issues

Steps to reproduce:

  1. Run minimal project

Minimal reproduction project: Physics.zip

qarmin commented 3 years ago

4.0 version of project - 4.0.zip

qarmin commented 3 years ago

Sometimes project freeze or works really slow so it is better to set used_nodes to 10 to speed up calculations and comment line random_functions() inside process_node()

qarmin commented 3 years ago

Also sometimes project freeze showing 

ERROR: get_supports: Condition "idx == -1" is true.
