Opcode 88 when making a Dictionary with Callable values in GDScript

Issue description

I have a Dictionary of ints to Callables. When this dictionary has more than one entry, I consistently get the error "Internal Script Error! Opcode: 88 (please report)".

The associated error message is this:

E 0:00:01:0088   player.gd:9 @ @static_initializer(): Condition ' p_instance == nullptr ' is true. Breaking..:
  <C++ Source>   modules/gdscript/gdscript_vm.cpp:2452 @ call()
  <Stack Trace>  player.gd:9 @ @static_initializer()

The exact GDScript that seems to be causing the issue is this:

static var flavor_fire_def : Dictionary = {
	Gummy.Flavor.UNFLAVORED : (func():
		pass),
	Gummy.Flavor.ORANGE : func():
		var bullet = preload("res://bullet.tscn").instantiate()
		get_parent().add_child(bullet)
		bullet.linear_velocity = -$Mesh/BulletSource.global_transform.basis.z * 3.0
		bullet.global_position = $Mesh/BulletSource.global_position
}

Unless I'm making a syntactical error somewhere, my only workaround is going to be assigning functions directly.

Steps to reproduce

The above code should theoretically be enough on my version, and perhaps OS.

Minimal reproduction project

The above data should cover it, I've seen no evidence that another part of my project is involved.

get_parent().add_child(bullet)
bullet.linear_velocity = -$Mesh/BulletSource.global_transform.basis.z * 3.0
bullet.global_position = $Mesh/BulletSource.global_position

Non-static functions and get_node() shorthands cannot be called in a static context. The bug is that the static analyzer did not report these errors in the lambda bodies.
