Setting breakpoint in flixel.graphics.FlxGraphic causes the program to crash.

[EliteMasterEric]

Reproduction Steps

1. Create a Flixel sample project, with this PlayState:

package;

import flixel.FlxG;
import flixel.FlxState;
import flixel.text.FlxText;

class PlayState extends FlxState
{
	override public function create()
	{
		super.create();

		var text:FlxText = new FlxText(0, 0, FlxG.width, "Hello World!");
		add(text);
	}

	override public function update(elapsed:Float)
	{
		super.update(elapsed);

		if (FlxG.keys.justPressed.SPACE)
		{
			FlxG.switchState(new PlayState());
		}
	}
}

2. Navigate to flixel/graphics/FlxGraphic.hx in your haxelib install folder.
3. Set a breakpoint at the beginning of the destroy() function. This line.
4. Run the program, then attempt to switch state.

Expected Behavior

The program should hit the breakpoint twice, then upon continuing the program should continue running.

Actual Behavior

The program hits the breakpoint for the first time, then after clicking continue, it hits the breakpoint a second time and a null object reference exception is thrown, and the program immediately ends.

Note that the program does NOT throw an exception if the breakpoint is not placed, and therefore this is an issue with the Visual Studio Code extension and not the program or library.

I see the following output from the program:

hxcpp/debug/jsonrpc/Server.hx:86: Debug Server Started:

I think it's a hxcpp debugger's problem? https://github.com/vshaxe/hxcpp-debugger
