Hi George,
There might be another reason for the crash. Could you first try to
replace on line 358 of negotiate_kerberos_pac.cc
ad_data = (krb5_data *)xmalloc(sizeof(krb5_data));
with
ad_data = (krb5_data *)xcalloc(1,sizeof(krb5_data));
Regards
Markus

Hi George,
I see now the cause. The Kerberos function krb5_free_data does not
check for NULL pointer before freeing. Here is a work around replace
krb5_free_data with:
if (ad_data) {
if (ad_data->data)
free(ad_data->data);
free(ad_data);
}
/* krb5_free_data(context, ad_data);*/
Regards
Markus

Can you type where at the gdb prompt after the crash. It should list the
