Quite a lot of noise in the two SOAP.pm cases:

$ fgrep -c 'SOAP.pm' /var/log/httpd/error_log
2380
$ fgrep -c 'Config.pm' /var/log/httpd/error_log
19
$ fgrep -c 'AuthorizeRequest.pm' /var/log/httpd/error_log
1

Additional information

I attach a patch which just adds defined($foo) to each of the tests. It is possible that you would prefer a pull request instead.

Obviously not very important in the grand scheme of things, but it would be nice to get this fixed when 6.2.64 is released
