Expected Behavior

Expected healthy compile and run

Current Behavior

I'm getting three different runtime (i guess) error depending on absolutely normal code changes

Failure Information (for bugs)

I was trying to implement ECS library. But at some point got stuck on this.

Steps to Reproduce

The error is really flaky and unpredictable. It may disappear on any code change. So please, try to reproduce by cloning the repo (branch: crap) and running make, repo: https://github.com/tymbaca/ecs/tree/crap

In cmd/main.odin there are 3 different main procedures, each will result in corresponding error:

package main

import ".."
import "core:fmt"
import rl "vendor:raylib"


WORLD := ecs.new_world(Component)

main :: proc() {
	mainSegFault() // <- change to any of main* proc below

	fmt.println("at the end of main") // this will not run
}

mainBus :: proc() {
	ecs.create_entity(
		&WORLD,
		Player_Control{},
		Movement{speed = 1.0},
		Box{size = {40, 50}, color = rl.RED},
		Transform{},
	)

	fmt.println("after entity create")
}

mainIlligal :: proc() {
	ecs.create_entity(
		&WORLD,
		Player_Control{},
		Movement{speed = 1.0},
		/*
		Box{size = {40, 50}, color = rl.RED},
		Transform{},
        */
	)

	fmt.println("after entity create")
}

mainSegFault :: proc() {
	ecs.create_entity(
		&WORLD,
		Movement{speed = 1.0},
		Box{size = {40, 50}, color = rl.RED},
		Transform{},
		Player_Control{}, // moved this to last position
	)

	fmt.println("after entity create")
}

mainOK :: proc() {
	ecs.create_entity(
		&WORLD,
		// Movement{speed = 1.0},
		// Box{size = {40, 50}, color = rl.RED},
		Transform{}, // this runs well LOL
		// Player_Control{},
	)

	fmt.println("after entity create")
}

The ecs.create_entity is pretty much a dummy:

// create_entity creates new entity with specified components, adds it to world and returns it
create_entity :: proc(world: ^World($T), components: ..T) {
	// nothing happens here
}

I guess there is something wrong with the combination of generic type World -> Union type Component -> component: ..T

Are you still experiencing this issue? Having trouble reproducing it on Mac OS M2 and Linux. Might be finnicky like you said.
