I tried the code below on my systems (Windows 7 64-bit, ActiveState Perl 5.12.1 32-bit) without any issues.

use strict;

while (<>) {
  print "You typed:\n$_\n";
}

Output:

test
You typed:
test

Hello
You typed:
Hello

I realize that's not the same version of Perl, but just thought I'd share another data point with you.
