There's a bug in src/lib/krb5/rcache/rc_dfl.c that will be fixed in the
next release; it's a problem with some allocated memory being used after
it is freed, which is wrong but manages to work on some architectures.
Here's the modified code, starting at about line 540 of rc_dfl.c:
struct authlist *q;
char *name;
krb5_error_code retval;
krb5_rcache tmp;
krb5_deltat lifespan = t->lifespan; /* save original lifespan */
name = t->name;
t->name = 0; /* Clear name so it isn't freed */
(void) krb5_rc_dfl_close_no_free(id);
retval = krb5_rc_dfl_resolve(id, name);
free(name);
if (retval)
return retval;
retval = krb5_rc_dfl_recover(id);
