here's the fixed code: http://dpaste.dzfl.pl/5f7dfe237d1e

btw, you have a bug in your implementation:

  (cast(E*) malloc(a.length * uint.sizeof))[0 .. a.length])();

should be:

  (cast(E*) malloc(a.length * E.sizeof))[0 .. a.length])();

sorry, i'm bad in explanations, let the code speak for itself.
