Correction to my initial post:
I oversimplified the code example by snipping too much of
context. Here is an example, which fails both on Windows and
Linux:
module main;
import std.stdio, std.file, std.string, std.algorithm, std.range,
std.datetime, std.conv, std.typetuple;
int e67_1(string fileName = r"67.txt") {
// Read triangle numbers from file.
int[][] cell;
foreach (y, line; splitLines(cast(char[]) read(fileName))) {
auto row = new int[y+1];
foreach (x, token; split(line))
row[x] = to!int(token);
cell ~= row;
}
// Compute maximum value partial paths ending at each cell.
foreach (y; 1..cell.length) {
cell[y][0] += cell[y-1][0];
foreach (x; 1..y)
cell[y][x] += max(cell[y-1][x-1], cell[y-1][x]);
cell[y][y] += cell[y-1][y-1];
}
// Return the maximum value terminal path.
return cell[$-1].reduce!max;
}
void main()
{
try {
writeln(e67_1);
}
catch (Exception e) {
writeln(e);
}
}
Here is the message on Linux:
std.file.FileException@std/file.d(219): 67.txt: No such file or

Again, the file requested exists. I test that by adding other
functions (from my initial post) to the code above.
