Hmm.. I've compiled the OP's code and my own test code (below) and both times I get perror() and cout code interleaved. Not sure what I might be doing differently than the you guys. I've tried on both Fedora 29 (g++ v 8.3.1) and rpi (g++ v 6.3.0). Now I'm confused ...
$ cat errtest.cpp 
#include <iostream>
#include <cerrno>

using namespace std;

int main()
{
    for(errno= 0; errno < 4; ++errno) {
        cout << "errno = " << errno << endl;
        perror("Error");
    }
}
$ make errtest
g++ -Wall -Wextra -std=c++17 -O2    errtest.cpp   -o errtest
$ ./errtest 
errno = 0
Error: Success
errno = 1
Error: Operation not permitted
errno = 2
Error: No such file or directory
errno = 3
Error: No such process
