GDAL bindings for Golang DatasetRasterIO exception and RasterBands

I'm translating gdal2tiles to Go with Lukeroth/Gdal bidngings and a DatasetRasterIO call from Go bindings for GDAL spits out 2 color channel image (Red & Green). After one tile gets created, on the second pass of the function call, it throws an exception that full of hex addresses but not obvious answer.

EDIT: Its not creating any files now, it just keeps throwing this same exception as soon as it hits ds.IO(args...) and if it manages to go past it, it happens again on dsQuery.IO(args...). I modified the tilebands(bandCount int) argument and reduced its bandCount and it managed to pass but not create an image. Anything above 1 band throws the exception.

EDIT: The error is

Exception 0xc0000005 0x1 0xc000400000 0x7ff912b9c343

I've searched online with no luck, documentation is lacking and I've also tried contacting multiple people with no reply.

EDIT: This is my problematic block of code.

    checkError(err)

}

if len(data) != 0 { // if data

        dstile.IO(gdal.Write, wx, wy, wxsize, wysize, data, wxsize, wysize, tilebands, band_list, 0, 0, 0)
        dstile.IO(gdal.Write, wx, wy, wxsize, wysize, alpha, wxsize, wysize, tilebands, band_list, 0, 0, 0)

    } else {

        scale_query_to_tile(&dsquery, &dstile, tile_job_info.tile_driver, []string{options}, tilefilename)
        dsquery.Close()
        dsquery = gdal.Dataset{}
    }
}
out_drv.CreateCopy(tilefilename, dstile, 0, []string{}, nil, nil)
data = nil
dstile.Close()

I'm expecting for IO calls to read and write to their respective drivers and finally dump them out. After the every iteration of tile_details, base tiles should be generated and the next call should be creating the overview tiles (pyramid).
