            Turns out my server got D.O.S:ed by some script kiddie in the Netherlands. Updated ProFTPd, so it should be OK now. Anybody reading this and unaware of this vulnerability, read this announcement (http://www.proftpd.org/proftpd-announce-archive/01-03/msg00002.html).

            Re: Can't contact author & missing file
            Yep, there was a brief period where a faulty 2.66 was up there (a day, approximately). Also, my server was down during this weekend, so any mails directed there -may- have bounced. Finally, note that my email domain has changed, link-data.com is no longer active, use linkdata.se (if that was not the case).

            Can't contact author & missing file
            In the README it says a demo called test.c
            can be compiled and reviewed for tutorial
            purposes but the latest distribution did not have
            that file and when I tried to e-mail them my
            mail bounced.

            Hope someone is reading this, the header files
            were not very intuitive and I would really like
            to see a demo source.

            Definitely worth a try
            After trying a few other memory watchers, this is the one I have settled down with. It does not have as many features as other memory watchers, like dmalloc, but it is very quick to setup and use. It'll write to memwatch.log a list of unfreed memory, double freed memory, etc and point out the exact line number in which they occur. For double-freed pointers, it'll show you both places where it was freed. At the end of the logfile it provides a little summary of how many allocations the program made, how many bytes weren't freed etc.
