Title:
  zsh can causes ps to generate error message

Status in procps package in Ubuntu:
  Confirmed

Bug description:
  (ps|grep foo;echo)
  Signal 18 (CONT) caught by ps (procps-ng version 3.3.3).
  ps:display.c:59: please report this bug

  
  (ps;echo)  # works
  (ps|grep foo) # works
  (ps|grep foo;echo) # fails

  This behaviour seems to be caused by zsh since it is not observable
  using bash. Note too that this bug cannot be recreated on precise.

  zsh configuration is stock "system configuration" (run zsh for first
  time and select option (2) - system defaults).
