Come on! Run your program before posting it. It's still broken.

When I add the missing parens, it prints 1 to 100 (in order) on both Windows and Linux. No crashes. I tried many versions all the way back to 5.6.0 on Windows.

Note that it's possible that the numbers get printed out of order if one child executes faster than another. This can happen regardless of the OS. You can see it happen using the following code:

use strict;
use warnings;

my $max_process = 10;
my $processes = 0;
for my $count (1..100){
    wait if $processes >= $max_process;
    sleep(rand(3)),print($count."\n"),exit unless my $pid = fork;
    $processes ++;
}
