ZCPU HL-ZASM C structs don't work correctly

[EnoSkyFire]

1. The Problem

The current structs that are implemented do not work correctly. There are two issues. First issue is the struct returned in a function is not correct. Secondly, when I use #pragma CRT ZCRT with void main(){}, my returned struct gives an address value.

2. First issue - returning structs

DerelictDrone posted this image with working code were 2D vector addition is executed but in the result the register R2 should be 4 and not 3. I tested this code and I get the same result. The issue lies with returning the struct since outputting x and y within the function itself gives the correct values. source: (#17)

3. Second issue - using void main() {}
Furthermore, when I try using structs with #pragma CRT ZCRT and with void main(){} instead of the main label, the returned struct has an address value. See code and result below.

Code:

//#pragma set OutputFinalListing true
#pragma CRT ZCRT

//jmp main

struct vec2 {
    float x;
    float y;
};

vec2 addvec(vec2 v, vec2 v2) {
    v.x += v2.x;
    v.y += v2.y;
    return v;    
    
}

vec2 v;
vec2 v2;

//main:
void main() {
    v.x = 1;
    v.y = 2;
    v2.x = 3;
    v2.y = 4;
    
    MOV R0,v.x
    MOV R1,v.y
    OUT 0, R0
    OUT 1, R1
    
    v = addvec(v,v2);
    
    MOV R2,v.x
    MOV R3,v.y
    OUT 2, R2
    OUT 3, R3
    
    MOV R4,v2.x
    MOV R5,v2.y
    OUT 4, R4
    OUT 5, R5
    
    v2 = v
    
    MOV R6,v2.x
    MOV R7,v2.y
    OUT 6, R6
    OUT 7, R7
}

Result:
