  11 Bug-Description:
  12
  13 Readline-7.0 changed the way the history list is initially allocated to reduce
  14 the number of reallocations and copies.  Users who set the readline
  15 history-size variable to a very large number to essentially unlimit the size
  16 of the history list will get memory allocation errors
