[Users] Segmentation Fault with CarpetReduce

[Bruno Giacomazzo]

DG,
  if you could share the parameter file that would be useful in order to
try reproducing the error with standard Einstein Toolkit thorns. I do not
see any problem with the lines of code you posted in the email.

Do you get the same problem also when using Carpet without refinement
levels?

Best regards,
Bruno
