Hi all,
I'm on macOS 10.11.6 with dmd 2.081.2 and I've a problem with

No output, (zero bytes) in stdout.
If I use standard process to collect both stream with:
---
auto processPipes = pipeProcess(args, Redirect.all, null,
Config.none, workDir);
foreach (c; pipes.stdout.byChunk(100)) writeln(cast(string) c);
// <<<---- it halts here: stdout file is empty, but not EOF
foreach (c; pipes.stderr.byChunk(100)) writeln(cast(string) c);
---
Everything is fine if I don't redirect the stderr to a pipe.
Suggestions?
If you want to use asynch io - you'll have to fork and use
NONBLOCK output on the file descriptor.
I wrote this years ago (not sure if it still compiles tbh, but it
should)
