Just using a 4 line log file with these addresses (and the one below), QDNS doesn't crash for me, either creating the DNS cache file from scratch, or re-reading it

On my machine, QDNS resolved this to 
20163681 207.101.74.26 churchilldevelopment-churchilldevelopment-psr2081256.z74-
101-207.customer.algx.nö

So it exhibited the same error, but the outcome is slightly different. Perhaps that has something to do with the default Regional and Language settings in the control Panel. (Mine are all set to "English (United States)"). So the crash could be caused by the size of the file, or by the additional characters being generated by QDNS on your machine. 

What happens if you create a 1 line log file with just 207.101.74.26 as the address, and run QDNS against it? Does QDNS still crash?

Does Analog care about the presence of the EOF?
