Oh yeah, I haven't updated Phobos on it for a while, my attention 
most this year has been the dub thingy. Just did though.

Meanwhile I've got the latest version of dmd and made it working.

In theory that looks good. Unfortunatley it's a relativly young feature 
which my compilers don't know about yet (dmd 2.079 and ldc based on an 
even older version of dmd). So in practice I'll probably have to wait 
until the next release cycle of debian in spring 2019... (maybe for the 
time being I'll update dmd and use dmd for this small part instead of 
ldc, but I yet don't know how to tell CMake to use dmd for this one 
file... But I'll probably figure this out.)

I don't know what your "older version of dmd" was, but the earliest I 
can see it is 2.077.0.


Indeed, it was fixed in 2.077 (look for Bugzilla 17844 here: 
https://dlang.org/changelog/2.077.0.html)

I need to execute a program and capture stdout, which I hoped 
std.process.execute would do. But unfortunatly this command 
also captures stderr, which I need to be ignored. When looking 
at the implementation of std.process.execute I see, that I can 
probably do this by removing "Redirect.stderrToStdout" in the 
function executeImpl. But for that I have to copy lots of 
functions from phobos in my own code. Is there an easier way to 
do that?


[...]

Here my complete program:


import std.process;
import std.stdio;
import std.array;

int main(string[] args)
{
const result = execute(args[1..$]);
writeln(result[1].replace("\\","").replace(" ","\\s"));
return result[0];
}


Looks like `Config.stderrPassThrough` [1] should do what you want:

const result = execute(args[1..$], null, 
Config.stdErrPassThrough);
