 From lmem.c:

void luaM_free_ (lua_State *L, void *block, size_t osize) {
   global_State *g = G(L);
   lua_assert((block == 0) == (block == NULL));
   (*g->frealloc)(g->ud, block, osize, 0);
   g->GCdebt -= osize;
}

The lua_assert should (probably) be:

lua_assert((osize == 0) == (block == NULL));
