bug#1521: 23.0.60; Emacs losing values of variables

[Chong Yidong]

Hi Michael,

Have you encountered this bug?  I haven't, but I don't use ERC (this is
bug#1521 in the Emacs bug tracker).

 
  I've noticed that Emacs is losing values of the variables after sometime
  due to this I'm not able to use semantic and erc properly. Most of the
  times, I've experienced this with ERC and I experienced it only in Emacs
  CVS not in 22.x. When I tried to expand a nick in ERC which is currently
  showing #mysql channel, I got following error (bytecode string is
  replaced with ...):

  ,----
  | Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  |   pcomplete-erc-nicks(": " t)
  |   (append (pcomplete-erc-commands) (pcomplete-erc-nicks 
erc-pcomplete-nick-postfix t))
  |   eval((append (pcomplete-erc-commands) (pcomplete-erc-nicks 
erc-pcomplete-nick-postfix t)))
  |   pcomplete--here((append (pcomplete-erc-commands) (pcomplete-erc-nicks 
erc-pcomplete-nick-postfix t)) nil nil nil)
  |   pcomplete/erc-mode/complete-command()
  |   byte-code("...")
  |   pcomplete-completions()
  |   byte-code("...")
  |   pcomplete(1)
  |   call-interactively(pcomplete)
  |   erc-pcomplete()
  |   run-hook-with-args-until-success(erc-pcomplete)
  |   erc-complete-word()
  |   call-interactively(erc-complete-word nil nil)
  `----
  But if I do '/names' and then try to complete nick names in ERC, it
  completes as expected. So I think this is the problem with Emacs losing
  values of variables. This is not always reproducible.
