I have an application which creates a cache, stores a ticket and then
destroys the cache, but sometimes I get a SEGV. This is on OpenSolaris (but
I think the code is the same as the MIT code).
t@1 (l@1) signal SEGV (no mapping at the fault address) in
krb5_free_cred_contents at line 180 in file "kfree.c"
180 if (val->client) {
(dbx) where
current thread: t@1
=>[1] krb5_free_cred_contents(context = ???, val = ???) (optimized), at
0xd22ddf3b (line ~180) in "kfree.c"
[2] krb5_free_creds(context = ???, val = ???) (optimized), at 0xd22de11c
(line ~244) in "kfree.c"
[3] krb5_mcc_free(context = ???, id = ???) (optimized), at 0xd22b6e74
(line ~176) in "cc_memory.c"
[4] krb5_mcc_destroy(context = ???, id = ???) (optimized), at 0xd22b6f4a
(line ~214) in "cc_memory.c"
[5] krb5_cc_destroy(context = ???, cache = ???) (optimized), at 0xd22b8671
(line ~55) in "ccfns.c"
[6] krb5_cleanup(), line 813 in "test.c"
which is:
177 void KRB5_CALLCONV
178 krb5_free_cred_contents(krb5_context context, krb5_creds *val)
179 {
180 if (val->client) {
181 krb5_free_principal(context, val->client);
182 val->client = 0;
183 }
184 if (val->server) {
185 krb5_free_principal(context, val->server);
186 val->server = 0;
187 }
188
Do I need to check if the cache has credentials before a destroy the cache
?
