For what it is worth, I cannot repro this with Windows 7:

   $ value="$( date | cat )"; echo "$? <$value>"

Also, your example is poor. As you well know, "cat" in this case should be a
noop:

   $ date | cat
   Tue, Jul 11, 2017  6:20:53 PM

Perhaps you can provide a sane example that fails? Something like:

   $ date | sed s/M/Z/
