Just on a side issue, I prefer to make tests like this positive so I'd
write:
   static AvlTree_t const *AvlTree_node(
       void const *pk, AvlTree_t const *pL, AvlTree_t const *pR
   ) {
       AvlTree_t *pT = malloc(*pT);
         if (pT) {
           pT->pk = pk;
           pT->pL = pL;
           pT->pR = pR;
       }
       return pT;
   }
I'm not going to "make a case" for this (though I will if you want!) --
I just think it helps to see lots of different styles.

That is *more* error prone,

 I would be happy for you to expand on why you say that.
 

all the more so if it's not a 5 liner...

There is no such thing as expanding 40 years of professional experience in software engineering and programming and doing it properly since day one: just think about that code and what I said for what it's worth, in particular I haven't mentioned 5 liners by chance, things are quite more complicated not in vitro.
And please do not hold a grudge about that: it's not me who was trying to say how to write code... ;)
