 Without any information about your system, the parameters you used,
etc. it is rather difficult to judge, what the problem in your case
could be.

  However, the default diagonalizer (DivideAndConquer) is known to die
with segmentation fault for awkward cases. You could try to use the
slower but more robust compiler (Standard)
