Clearing credentials question

[Markus Moeller]

Hi

I have the following little program which seg faults when calling 
krb5_free_cred_contents.  The error seems to come from 
krb5_free_keyblock_contents(context, &val->keyblock);  Shouldn't 
krb5_free_keyblock_contents check if the content is not zero ?

Thank you
Markus


#include <krb5.h>

int main() {

krb5_context context = NULL;
krb5_principal client;
krb5_principal server;
krb5_creds  creds;

char *cclient="markus at SUSE.HOME";
char *cserver="krbtgt/SUSE.HOME at SUSE.HOME";

krb5_error_code code = 0;

code = krb5_init_context(&context);

code = krb5_parse_name(context, cclient, &creds.client);
code = krb5_parse_name(context, cserver, &creds.server);

krb5_free_cred_contents(context, &creds);

}
