Didn't you make changes to how and when the global PRNG is popped and accessed in randomShuffle? I figured it *could* be an explanation.
No, it was partialShuffle that I tweaked, and that shouldn't affect the results here. There was a bug where partialShuffle would _always_ shuffle the whole of the input; but that wouldn't affect the results of randomShuffle itself, which calls partialShuffle with the explicit request to shuffle the entire array.
Just to be sure I checked with random/partialShuffle pre- and post- my patches, and the result is identical: [1, 8, 4, 2, 0, 7, 5, 6, 9, 3] just as the OP gets for dmd.
I think it's more likely that the culprit is either your set of patches to the Mersenne Twister, or the patches made to uniform() (which is called by partialShuffle). I'll look more deeply into this.
