golang 调用C++动态库 提示fatal: morestack on g0

[实况灬天河]

如题，我想请问一下，这个g0是啥呀？我以为是因为栈空间不够大，在网上找了扩栈的方法，尝试过后，还是不能解决。关键源码如下：

//加载动态库
	ImageComparison ,err := syscall.LoadLibrary("ImageComparison.dll")
	if err != nil{
        print("LoadLibraryfailed:",err.Error())
    }
	defer syscall.FreeLibrary(ImageComparison)
	lpfnImageComparison,err:= syscall.GetProcAddress(ImageComparison, "ImageComparison")
	if err != nil{
        print("GetProcAddressfailed:",err.Error())
    }
	ret, _,_:= syscall.Syscall(lpfnImageComparison,2,uintptr(unsafe.Pointer(syscall.StringToUTF16Ptr(file_dir+"r.jpg"))),uintptr(unsafe.Pointer(syscall.StringToUTF16Ptr(file_dir+"v.jpg"))),0)
	if ret == 0 {
		c.Data["json"] = map[string]interface{}{"result": "0"}
		c.ServeJSON()
		return 
	}
