[Gmsh] Gmsh exits immediately after run, "Requesting more near neighbors than data points"

Wed Feb 3 16:00:22 CET 2016

It appears to be a regression of some sort. There is more info on the
previously linked git issue thread.

The author there states that it works with gmsh 2.9.3 and getdp 2.5.1 and
was able to reproduce the issue with the newest versions of the tools.
