bug#23987: 24.5; Icy with Ggtags Problem

[B.V. Raghav]

======================================================================
Start with a project having GTAGS table, and then starting with
`emacs -Q', navigate to the project :

1. Load the ggtags (in scratch buffer type the following, and `C-M-x'):
   (add-to-list 'load-path "~/.emacs.d/elpa/ggtags-20151214.1344")
   (require 'ggtags)

2. Navigate to a file in project, and `M-. <defin..> TAB RET' --- moves
   to <definition> in the corresponding file.

3. Close emacs `C-x C-c'

Restart `emacs -Q'

1. Load ggtags, and icicles, as in step 1 of prev attempt.

2. Navigate to a file in project, and `M-. <defin..> TAB RET' ---
   crashes with following error:

   Error running timer `compilation-auto-jump': (error "Selecting
   deleted buffer")



Can anyone reproduce this?



This has been there for a long time. May be related to
https://github.com/leoliu/ggtags/issues/89

There is a workaround suggested in the above link,

> Does it help if you change 0 in (ggtags-navigation-mode-cleanup buf 0)
> of ggtags-global-handle-exit to a greater value, for example, 0.25, 0.5,
> 1 etc?

but it did not work for me.
