This issue was reported on the Python extension repo so I'm manually "transferring" it here: microsoft/vscode-python#23639

Type: Bug

Version: 1.90.1 (user setup)

#include<thread>
#include<iostream>

void hello() {
    std::cout << "hello" << std::endl;
}

int main() {
    std::thread t{hello};
    t.join();
    return 0;
}

I write a simple program using std::thread, and compile it with g++.
This .exe file works fine in single cmd.exe, but does not print anything in integrated terminal in vscode
g++ comes from MinGW posix thread model

in external cmd, the a.exe can print "hello"

but in integrated cmd, the a.exe doesn't print anything

and .exe works with a New Window VSCode
