Yes, it does. Without optimizations the result is "ndgorsfesnywaiqraloa", while with optimizations the result is always "aaaaaaaaaabbaaaaaaaa".

Sorry for taking so long. So problem is uniformR. You can reproduce bug reliably and I cannot. Are you on 32-bit system? I only tested on 64-bit ones. If this isn't the case I'm out of ideas.
