auto file = File("test.csv", "r");
auto records = csvReader!double(file.byLine().joiner("\n"));
writeln(records);

The last line throws a CSVException due to some conversion error
'Floating point conversion error for input "".' for the attached input.

If you change the input to
3.0
4.0
you get no exception but wrong a output of
[[4], [4]]
.

Using readText or
auto records = csvReader!Record(["3.00", "4.0"].joiner("\n"));
works as expected.

Can you reproduce the issue? I'm running dmd2.059 on Linux.
Thanks.
