If I set KRB5_CCNAME to an empty file (eg /dev/null or a truncated regular file) then krb5_cccol_have_content leaks the 'cache' local variable, because krb5_cc_start_seq_get returns an error.

I'm seeing this on krb5 1.12 but looking at the trunk code the issue seems to be the same.

It's obviously low priority since a truncated ticket cache isn't a normal phenomenon, but ran into this and figured I'd report it.
