Inheriting classes won't call constructor of their super class

[kyasbal]

I have written this bunch of code to operate texture passed from WebGL.

export class U8_4 {
  constructor(public x: u8, public y: u8, public z: u8, public w: u8) {}
}

export class Texture {
  public baseAddress: u32 = 0

  public width: u16 = 0

  public height: u16 = 0

  public ch: u8 = 0

  constructor(width: u16, height: u16, ch: u8) {
    this.baseAddress = memory.allocate(<u32>(width * height * <u16>ch))
    this.width = width
    this.height = height
    this.ch = ch
    //*************************************************
    //There are problems here
    //*************************************************
    console.logi(123456) // This logging is not called
  }

  public getAddressAt(i: u16, j: u16): u32 {
    return (<u32>i * <u32>this.width + <u32>j) * <u32>this.ch
  }
}

export class Texture4CH extends Texture {
  constructor(width: u16, height: u16) {
    super(width, height, 4)
    console.logi(width)
    console.logi(height)
  }

  public getAt(i: u16, j: u16): U8_4 {
    let ba: u32 = this.getAddressAt(i, j)
    let x: u8 = load<u8>(ba, 0)
    let y: u8 = load<u8>(ba, 1)
    let z: u8 = load<u8>(ba, 2)
    let w: u8 = load<u8>(ba, 3)
    return new U8_4(x, y, z, w)
  }

  public setAt(i: u16, j: u16, col: U8_4): void {
    let ba: u32 = this.getAddressAt(i, j)
    store<u8>(ba, col.x, 0)
    store<u8>(ba, col.y, 1)
    store<u8>(ba, col.z, 2)
    store<u8>(ba, col.w, 3)
  }
}

As you can see, I have inherited Texture class from Texture4CH. When I instanciate Texture4CH class, the super notation super(width, height, 4) seems not working as intended.
Is this intended limitation of assemblyscript?

Class support is still relatively basic and when looking at the generated text format it appears that the super call is compiled incorrectly. Seems that its arguments are compiled, but just dropped instead of calling anything with them.

 (func $tests/compiler/empty/Texture4CH#constructor (; 6 ;) (type $iiii) (param $0 i32) (param $1 i32) (param $2 i32) (result i32)
  (local $3 i32)
  (drop
   (get_local $0) (; this ;)
  )
  (drop
   (get_local $1) (; width ;)
  )
  (drop
   (get_local $2) (; height ;)
  )
  (drop
   (i32.const 4) (; 4 ;)
  )
  ...

I haven't tried yet, but can we work around this by using a method instead of relying on constructors? F.e. an init method that you just have to remember to call, const foo = new Foo(); foo.init();.

@dcodeIO could we close this as well?

[dcodeIO]

Yeah, should be fixed meanwhile. Feel free to reopen if there are still any issues!
