[Ctags] ctags generating corrupt tags file

[Jean J. <jea...@gm...>]

Hi all

Exuberant Ctags 5.9~svn20110310, Copyright (C) 1996-2009 Darren Hiebert

After generating a tag file, tag lookup fails:

:tag Tr...
E431: Format error in tags file "tags"
Before byte 51

The file starts like this:

"""

    // strip json vulnerability protection prefix
    data = data.replace(JSON_PROTECTION_PREFIX, .useApplyAsync
src/Orchard.Web/Modules/Orchard.Resources/Assets/Js/Angular/angular.js
   /^var JSON_PROTECTION_PREFIX = \/^\\)\\]\\}',?\\n\/;$/;"    f
    data = data.replace(JSON_PROTECTION_PREFIX, .useApplyAsync
src/Orchard.Web/Modules/Orchard.Resources/Scripts/angular.js    /^var
JSON_PROTECTION_PREFIX = \/^\\)\\]\\}',?\\n\/;$/;"    f
  if (isString(data)) {
!    lib/typescript/tsc.js    /^        "^": 44 \/* CaretToken *\/,$/;"    p
!    src/Orchard.Web/Modules/Amba.ImagePowerTools/Scripts/angular-last.js

When I delete everything before `!_TAG_FILE_FORMAT` it works fine.
Is this a bug? Is there a workaround?
