Native Code Generation Failure: internal lowering failure

[Meifeng1510]

I encountered an error while trying to compile a script. The error message indicates a native code generation internal lowering failure

Native code generation of script =ServerScriptService.lowering failure failed:  
Native code generation failed to compile some of the module functions:
Function '(anonymous)' at line 1 encountered an internal lowering failure.
Script will be interpreted.

The script causing the issue is as follows:

--!native

local TRUE_CONST = true
TRUE_CONST = TRUE_CONST

local tbl = {}
for i = 1, 1 do i=i end

local function func() return TRUE_CONST end

function tbl.Unary() end
function tbl.Add() end
function tbl.Subtract() end
function tbl.Multiply() end
function tbl.Divide() end
function tbl.Power() end
function tbl.Modulo() end
function tbl.LessThan() end
function tbl.EqualTo() end
function tbl.LessThanOrEqualTo() end
function tbl.GetDigitsCount() end

tbl.Concatenate = tbl.something

local anotherTbl = {
	[1] = function() end,
	[2] = function() end,
}

local ClassMeta = {

	__tostring = tbl.something,
	__concat = tbl.Concatenate,
	__len = tbl.GetDigitsCount,
	__unm = tbl.Unary,
	__add = tbl.Add,
	__sub = tbl.Subtract,
	__mul = tbl.Multiply,
	__div = tbl.Divide,
	__mod = tbl.Modulo,
	__pow = tbl.Power,
	__eq = tbl.EqualTo,
	__lt = tbl.LessThan,
	__le = tbl.LessThanOrEqualTo,

}

Most of the unnecessary code that is not related to the issue has been removed.

Steps to Reproduce: Compile the script with native code generation
Expected Behavior: The script should be compiled and executed natively without errors.
Actual Behavior: The script fails native code generation with the above error message and is interpreted instead.

Thanks for the report.
We are able to reproduce the issue and the code that causes it.
It's a bit similar to a different open issue we have, but I'll keep it open as an extra example and progress tracking.
Will be working towards fixing this soon.
