New description:

 The development version of Carpet uses vectorisation to speed-up
 prolongation.  This fails with various errors, including corruption of the
 malloc heap.

Comment:

 I have made

 LoopControl::use_random_restart_hill_climbing = no

 the default in Carpet since this seems to avoid the segfault.
