Hi there,
The following code:

void main(){
   import std.array : array;
   import std.stdio : writeln;
   import std.random : rndGen, randomShuffle;
   import std.range : iota;

   rndGen.seed(12);
   int[] temp = iota(10).array;
   randomShuffle(temp);
   writeln(temp);
}

writes [1, 8, 4, 2, 0, 7, 5, 6, 9, 3] if it's compiled with dmd,
but [1, 7, 4, 6, 2, 9, 5, 0, 3, 8] with gdc.

Are you sure you are compiling with the same version of dmd and 
gdc? Fixes were made to the rand.d library in the latest release, 
which could explain the difference you are observing.
