This doesn't appear to be due to segments, but rather due to the small min/max range of the segments, which is causing an inordinate number of invalid individuals.  However that should *not* be an issue, so we'll look into what the initialization issue is.

Using the latest snapshot from GitHub, I find that, if I use segments in my genome, CMA-ES silently gets stuck before the first generation is evaluated.

Attached is a MWE.

I'm guessing that some background thread has silently crashed while the main thread was waiting for it?
