#1322: varnishd master segfault when parsing <=varnish-3 director vcl
---------------------------+----------------------
 Reporter:  jw             |       Type:  defect
   Status:  new            |   Priority:  normal
Milestone:                 |  Component:  varnishd
  Version:  trunk          |   Severity:  normal
 Keywords:  vcl, director  |
---------------------------+----------------------
 varnish master fails to parse an old style vcl if it contains any director
 (doesn't really matter which or how it is configured).
