[Bug] Compiler fails with wrong return type for operator

[zerkawei]

The following code fails to build on Linux (couldn't reproduce on Windows) :

public struct FooBar
{
	public const Self Const = .(); // Has to be const

	public static Bar operator+(Self a, Object b) // Has to be an operator that returns Bar
	{
		return default; // Return value not relevant
	}

}

public struct Foo
{
	protected float[1] e; // Has to be fixed size array (size not relevant) of float or double
}

public struct Bar : Foo // Has to be derived
{
}

public class Program
{
	public static void Main()
	{
		Bar required = .(); // Has to be a new Bar instance

		let error = (FooBar.Const + null); // Has to involve at least one const FooBar (other value not relevant)
	} 
}

With the following error :

Function return type does not match operand type of return inst!
  ret float %2, !dbg !37
 i32

Inspecting the IR shows that the operator is incorrectly marked has returning i32 rather than float here

define i32 @_ZN2bf8TestZone6FooBarplES1_PNS_6System6ObjectE(ptr %b) #0 !dbg !4 {

Tested on latest nightly (03/27/2026)
