I have this somehow reduced program that behaves differently on osx and
linux.
```d
void stdioMain()
{
import std.stdio : readln, writeln;
import std.concurrency : spawnLinked, receive, receiveTimeout,
LinkTerminated;
import std.variant : Variant;
import std.string : strip;
import std.process : execute;
import core.time : dur;
auto input = spawnLinked(() {
string getInput() {
writeln("Please enter something:");
return readln().strip();
}
string line = getInput();
while (line != "quit")
{
writeln("You entered ", line);
line = getInput();
}
});
bool done = false;
while (!done) {
auto result = ["echo", "Hello World"].execute;
if (result.status != 0)
{
throw new Exception("echo failed");
}
writeln(result.output);
receiveTimeout(dur!"msecs"(-1),
(LinkTerminated t) {
writeln("Done");
done = true;
},
);
}
writeln("ByeBye");
}
void main(string[] args)
{
stdioMain();
}
`
It should just read from stdin in one separate thread and on the main
thread it just executes one `echo` after the other (and tries to find
out, if the other thread finished).
In linux this behaves as expected, meaning it prints a lot of hello worlds.
In osx on the other hand it prints 'please enter something', waits for
my input, prints it, and outputs one hello world.
What did I do wrong?
Kind regards,
Christian
p.s.: i am using ldc-1.35.0 osx version is 13.6.
