PhysicalDevice::get_image_format_properties sets the stencilUsage-member in this code block to 0:

if (m_extension_info_ptr->get_device_extension_info()->ext_separate_stencil_usage() )
{
    VkImageStencilUsageCreateInfoEXT create_info;

    create_info.pNext        = nullptr;
    create_info.stencilUsage = 0;
    create_info.sType        = VK_STRUCTURE_TYPE_IMAGE_STENCIL_USAGE_CREATE_INFO_EXT;

    image_stencil_usage_create_info_struct_id = input_struct_chainer.append_struct(create_info);
}

This is not allowed according to the specification and throws a validation error in the latest Vulkan SDK version:
