I spun up a Ubuntu vm and in works correctly there. Thanks.

Re: warning: pointer not aligned at address
Conveniently the site is down immediately after I posted that so
here is the code to which I was referring:
import std.stdio, std.algorithm, std.range;
enum DoorState : bool { closed, open }
alias Doors = DoorState[];
Doors flipUnoptimized(Doors doors) pure nothrow {
doors[] = DoorState.closed;
foreach (immutable i; 0 .. doors.length)
for (ulong j = i; j < doors.length; j += i + 1)
if (doors[j] == DoorState.open)
doors[j] = DoorState.closed;
else
doors[j] = DoorState.open;
return doors;
}
Doors flipOptimized(Doors doors) pure nothrow {
doors[] = DoorState.closed;
for (int i = 1; i ^^ 2 <= doors.length; i++)
doors[i ^^ 2 - 1] = DoorState.open;
return doors;
}
void main() {
auto doors = new Doors(100);
foreach (const open; [doors.dup.flipUnoptimized,
doors.dup.flipOptimized])
iota(1, open.length + 1).filter!(i => open[i -
1]).writeln;
}
warning: pointer not aligned at address
When compiled with any dmd compiler from 2.069.0 through present (2.074.0), https://rosettacode.org/wiki/100_doors#D produces the following linker warning: ld: warning: pointer not aligned at address 0x10004FCEB (_D51TypeInfo_S3std5range13__T4iotaTiTmZ4iotaFimZ6Result6__initZ + 24 from doors100.o) [65 other lines removed for brevity] ld: warning: pointer not aligned at address 0x100050C7D (_D11TypeInfo_xb6__initZ + 16 from doors100.o) specific compilers checked: dmd-2.068.0 dmd-2.068.1 dmd-2.068.2 dmd-2.069.0 dmd-2.070.0 dmd-2.071.2 dmd-2.073.1 dmd-2.073.2 dmd-2.074.0 What's the proper way to address these warnings? The code is linked and works as expected but, to me, there is just something about those warnings that cries out for attention. Is there something I can do to align this code or is this something that needs to be addressed in the compiler? Thanks, Andrew
