> Hi Henry, Tucker and everyone,
>
> Parts modules in our project are using new components in trunk and we are
> going to compile them to LZO.
>
> As you can see from the build script error, it can be compiled into LZO
> successfully but fail when compiling the whole project and throw a BOM
> error.

> The reason of the error may lie in while handling the reference of new
