Missing variables are not always skipped

[ghost]

CSV Compare does not skip variables which aren't present in both csv files in some cases. For example the following base.csv:

time;a;b;c
0;1;2;3
1;2;3;4
2;3;4;5
3;4;5;6
4;5;6;7

and actual.csv:

time;a;x;c
0;1;0;3
1;2;0;4
2;3;0;5
3;4;0;6
4;5;0;7

Note that b exists in base.csv but not in actual.csv, and x is missing from base.csv but exists in actual.csv. In the generated report the variable b is listed with a 100% success rate. This is a rather severe bug since the user get the impression that everything is fine and the variable produces the correct result! It does however leave a warning in the log, saying that b has been skipped (which it apparently haven't). Log:

2015-07-07Z13:16:51 [     Warning ] b not found in "actual.csv", skipping checks.

Command used:

Compare.exe actual.csv base.csv -r out
