I have not found a hack-free solution yet.  Here are some other things I've tried that would be less hackish, but have all failed:
 - Replace \\ with \tabularnewline :: Same behavior as with \\
 - Replace \\ with \\{} :: Extra horizontal space before the *
 - Replace \\ with \tabularnewline{} :: Same behavior as \\{}

I just now tried another solution that does work, but may still be considered a hack.  In short, use the optional argument explicitly:
 - Replace \\ with \\[0pt] :: This has the expected behavior for the * and for the spacing
