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

I am reducing the priority, and still hope to get to the bottom of this before the release.

Comment (by Roland Haas):

Datura and Damiana (the clusters mentioned here) no longer exists. However most clusters by now use VECTORIZE=yes by default and the issue is not seen there. The parameter use_random_restart_hill_climbing no longer exists, its function having (likely) been taken over by use_random_restart_hill_climbing which defaults to 0 since otherwise LoopControl remembers too many tries, becoming slow and using too much memory (the likely cause of the issue here).
