C++ Pipe command Emulation works on Linux, not MacOS

[sand kindle]

I'm trying to write a program that executes the command below:
ps -A | grep <string> | wc -l

On MacOS, the program stalls somewhere after line 45, which reads
cout << "I'm a great-grandchild" << endl;

But when I run into a Linux machine (I ssh into it), it runs perfectly fine.

Why is this?

What's the point of commenting out the whole code?

Have you tried using a debugger

The grey background is Linux output, blue is MacOS

I can't seem to debug into forked child, it only stays in parent

using VSCode debugger

In gdb you can set it to follow forks

You can do that when using gdb via vscode too

mm ok, I use clang++ so idk if I'll have to switch entirely

Gdb can debug anything, it doesn’t matter what compiler you used

You can also follow forks in lldb if you’re using that

Another useful debugging tool is strace
