Failed to create xrt bo using host memory

[jasvinderkhurana]

I am trying to create a xrt buffer object using host memory and it is failing with error as "bad alloc". Can someone please guide what is the issue.

Host code:

    // Allocate buffer based on the image size
    size_t buffer_size = 1280 * 720;  // Adjust the size based on your actual image

    void* buffer_left;
    posix_memalign(&buffer_left,4096, buffer_size);

//    unsigned char* buffer_left = (unsigned char*)malloc(buffer_size);

    if (load_png_to_memory(filename, (unsigned char*)buffer_left, buffer_size, &width, &height, &color_type) != 0) {
        printf("Error loading PNG to memory\n");
        free(buffer_left);
        return -1;
    }

    auto device = xrt::device(0);
    auto uuid = device.load_xclbin("stereolbm_accel.xclbin");
    auto stereo_accel = xrt::kernel(device, uuid.get(), "stereolbm_accel");

   try{
    auto m_buffer = xrt::bo (device, buffer_left, buffer_size, stereo_accel.group_id(3));
   }
    catch (std::exception &e) {
      LOG (FATAL) << "Unable to create Buffer: " << e.what();
    }

The error I am getting is:
