Hi,

When checking your case.struct file, first I did not believe it but then
it turned out to be true:

/tmp/cub23> grep rmt cub23.struct

You really want to calculate Cu with RMT=0.2 bohr  ???


This leads to errors in lstart

  NSTOP= 362  FOR THE ORBITAL  4S

Therefore case.rsp is not complete and dstart crashes.

PS: Use for Cu a 10-20% larger RMT than for B. (Check the FAQ-page why
you should do that).
