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

Yes, and it seems .joiner isn't as lazy as I'd have thought. 
byLine() reuses its buffer so it will overwrite previous lines in 
the file. This can be resolved by mapping a dup to it.

import std.stdio;
import std.algorithm;
import std.csv;

void main()
{
    struct Record {
        double one;
    }
    auto filename = "file.csv";
    auto file = File(filename, "r");
    auto input = map!(a => a.idup)(file.byLine()).joiner("\n");
    auto records = csvReader!Record(input);
    foreach(r; records)
    {
        writeln(r);
    }
}
