I found the documentation http://valgrind.org/docs/manual/quick-start.html but the example under "4. Interpreting Memcheck's output" is with malloc whereas my output is with free:
==9729== Invalid read of size 4 ==9729== at 0x40DD82D: stash_as_reply (get_in_tkt.c:321) ==9729== by 0x40DDFDE: krb5_get_init_creds (get_in_tkt.c:1263) ==9729== by 0x40DF3D2: krb5_get_init_creds_keytab (gic_keytab.c:108) ==9729== by 0x80897FC: krb5_create_cache (xxx.c:1167) ==9729== by 0x8050AD8: main (xxx.c:368) ==9729== Address 0x45954c4 is 4 bytes inside a block of size 84 free'd ==9729== at 0x4026BFA: free (in /usr/lib/valgrind/x86-linux/vgpreload_memcheck.so) ==9729== by 0x40E3790: krb5_free_creds (kfree.c:221) ==9729== by 0x80897A8: krb5_create_cache (xxx.c:1160) ==9729== by 0x8050AD8: main (xxx.c:368) How do I interpret this ?
