- MoonlightSentinel (10/12) Jul 05 2021 Yes, use [`get`](https://dlang.org/phobos/std_net_curl.html#.get):

- z (6/27) Jul 07 2021 On 64 bits you don't even get a stack trace or description.
- rikki cattermole (4/33) Jul 07 2021 With ldc you can turn on address sanitizer which will give you that
- notna (2/6) Jul 07 2021 compiling with ldc2 "just works"! thanks for the hint ;)
- notna (28/33) Jul 07 2021 Well, that's an option, for those who want and are knowledgeable
- MoonlightSentinel (6/10) Jul 07 2021 It's hard to give proper error backtraces without debug

Let's say I can't store information into files.
Is it possible to download a file into an array.
This is what I have now. It saves a download into a file named:
file.txt
import std;
import std.net.curl;
void main()
{
writeln("Hello D");
download("https://gist.githubusercontent.com/deekayen/4148741/raw/98d35708fa344717d8eee15d11987de6c
e26d7d/1-1000.txt", "file.txt");
}
Also run.dlang.io seems to be blocking and not letting me to run
curl requests. I'm feeling sad right now.

Sad, i know. If you want better i could recommend you to compile with `-g` and hook up a debugger, then just let it run and it should triger a breakpoint on 0xC0000009(access violation).

Anyways, I can reproduce the error when compiling with `-m32` (the default), using `-m32mscoff` and `-m64` works as expected. You should probably avoid `-m32` in general (as dub does btw).
