I have a file with empty lines: 2,3 and 5,6

filename.csv (with linenumbers for better view in this message)
1>Joe,Carpenter,300000
2>
3>
4>Fred,Blacksmith,400000
5>
6>

Now, if I run:
rdmd --eval='"filename.csv".File.byRecord!(string,string,int)("%s,%s,%d").writeln'

It prints:

[Tuple!(string, string, int)("Joe", "Carpenter", 300000),
 Tuple!(string, string, int)("Joe", "Carpenter", 300000),
 Tuple!(string, string, int)("Joe", "Carpenter", 300000),
 Tuple!(string, string, int)("Fred", "Blacksmith", 400000),
 Tuple!(string, string, int)("Fred", "Blacksmith", 400000),
 Tuple!(string, string, int)("Fred", "Blacksmith", 400000)]

It happens because code in

https://github.com/dlang/phobos/blob/master/std/stdio.d#L297

not checks return value after call formattedRead.

Is this a bug? Or I not understand something?

Yes, I think it's a bug.
