Curious bug

Here's a Maple bug:

If you define the function f(x) = (5 - y) ^ (4/3), then try to evaluate it at f(-3), you get the wrong answer.  To get the right answer you must evaluate it at f(-3.)  Of course we know that Maple distinguishes between exact answers & decimal answers, but both answers are supposed to be the same.  In the first case, you get 88^(1/3); in the second, the correct answer of 16.0. 

Anyone know what's going on?
