What alleged bug did you have in mind?

Did something not work as expected with Print in an earlier version. And why use print at all? Just the DSolve expression by itself will give the same output.  In Mathematica 9.0.1, this is:

      DSolve[{u'[t] == 2*Sqrt[u[t]], u[0] == 0}, u[t], t]
   (* {{u[t]->t^2}} *)

which, of course, is valid only for t >= 0.
