>Christian should use a fixed time

I'd say GSTS should work even in that case (provided it is the source of the crash), and it is not too difficult to fix.
I'm not really sure PWave timestep is accurate for Hertz contact, is it?

  You can reproduce the bug with the attached script (similar to the one i submitted with version 2960).
  First try to set Law2_ScGeom_MindlinPhys_Mindlin(neverErase=False), this will work.
  Then set neverErase=True and yade crashes.
