The failure in static analyzer looks to me like a false positive:
```
 pubkey.c:1499:35: warning: Access to field 'data' results in a dereference of a null pointer (loaded from variable 'y')
            (&key->params.params[ECC_Y], y->data, y->size)) {
                                         ^~~~~~~
```
This is in `gnutls_pubkey_import_ecc_raw()`, which is called only from `gnutls_pubkey_import_ecc_eddsa()` with `GNUTLS_ECC_CURVE_ED25519` curve, which is not going into this branch at all.
