The module rd_cred.c frees up the ticket which was just received via
a forward operation.
The code at lines 173, 174
pcur->ticket = *pdata;
krb5_free_data(context, pdata);
copy the length and pointer to the data to the pcur->ticket, then
krb5_free_data frees both the krb5_data structure and the data.
This should be changed to
krb5_xfree(pdata);
so as to only free the krb5_data structure, and not the data which the
pcur->ticket is still pointing at.
This appears to be the cause of the ASN.1 identifier problems which
some of us have seen while trying to use forwarded credentials.
