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.

I finally wrote test case that doesn't depends on anything besides
mwc-random (it's
in attachment). Could you check whether it still triggers the bug
