Checking the code, it fails before to return anything. Running crosss-link, that
fails in the same function:
./cross-link

init_memory_pool(): invalid pool
Init memory pool returns -1 bytes
   0"000.041| BUG in heapobj_pkg_init_private(): [main] cannot initialize TLSF
memory manager


I just added:

+      printf("Init memory pool returns %zd bytes \n", available_size);

        if (available_size == (size_t)-1)
                panic("cannot initialize TLSF memory manager");

+     printf("Running after ...\n");


in that function of the file you mentioned.
