Latest working version of Haxe I can use for my Heaps/Hashlink projects is `4.1.5`. With any newer versions of Haxe, the .hl file it produces (even on a basic new hxd.App) creates a program that, as best as I can explain, does absolutely nothing. Regardless of where I compile it from HaxeDevelop or via the CLI, the program does nothing on boot, and when using HaxeDevelop, I get a terminal that ends on “press any key to continue…”

Minimum needed to reproduce this is as follows:

```haxe
package;

import hxd.App;

class Main extends App
{
	
	static function main() 
	{
		new Main();
	}
	
	public function new()
	{
		super();
	}
}

```

This should create a new window with a black background, using the haxelibs `heaps`, `hlsdl`, and `hlopenal`. On Haxe 4.1.5, this runs as expected, anything newer produces the aforementioned problem of “doing nothing”. Problem does not occur with JavaScript target, C target is unknown because I have never been able to compile a HLC program to begin with.

This worked, thank you.
