Details:

I did not read enough code to be able to say conclusively can the deref
happen.

if (!ctx || !ctx->session_data || gnutls_session_set_data (session,
ctx->session_data->data, ctx->session_data->size))
{
    /* server does not want to continue the session */
    gnutls_free (ctx->session_data->data);
