You can't draw from your experiment the conclusion that Perl doesn't have a problem with random numbers. Perl does *not* generate random number itself, it will let the OS do that for it. Looking at Configure, Perl will try to use drand48(), random() or rand(), in that order (unless configured manually otherwise).

So, the best you can conclude there's no problem with whatever function Perl is using on your system. It might be different on other platforms
