sizeof(*reo_item) like the one you do on the next line.
Failure test.

Having two allocs here is needless. embed the REOBJECT structure
inside ME_ReObjItem.

I don't think this is a useful optimization. It's probably also hiding
a bug below.

At this point reo_item_prev could be NULL, if it would be the first
item in the list.

As already suggested this become REOBJECT reobj

Let's drop the ME_ noise and the typedef and go for:
struct re_object
{
struct list entry;
REOBJECT obj;
};

Why are you sneaking this change in here? It should be a separate patch.
