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@SUSE.HOME";
char *cserver="krbtgt/SUSE.HOME@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);
}
