hi,
i have discovered an problem regarding the openpgp functions.
if i try to set openpgp credentials by using the abstract functions gnutls
segfaults.
gnutls_pcert_st pcert;
gnutls_privkey_t pkey;
gnutls_privkey_init(&pkey);
r = gnutls_pcert_import_openpgp_raw(&pcert, &pub_data,
GNUTLS_OPENPGP_FMT_RAW, keyid, 0);
r = gnutls_privkey_import_openpgp_raw(pkey, &priv_data,
GNUTLS_OPENPGP_FMT_RAW, keyid, nullptr);
r = gnutls_certificate_set_key(cre, nullptr, 1, &pcert, 1, pkey);
the last function will cause a segfault in cdk_kbnode_walk(). the keyid is
specified correctly. the import functions return success. then pgp-key contains
a master key and one single subkey.
