Subject: if krb5_get_default_config_files() returns success and
X-Git-Tag: krb5-1.10-alpha1~125
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=259668e4970e05226efa1807303d3adfbb35df4a;p=krb5.git

if krb5_get_default_config_files() returns success and
an empty list, then get_profile_file() will attempt
to dereference a null pointer.  check for the empty
list and treat it as failure.
