Segfault caused by typo in query:

[Buchhold]

Happened for a query for politicians who had an audience with the pope on the clueweb+freebase dataset. Would probably happen for all queries that make words look like variables.

PREFIX fb: <http://rdf.freebase.com/ns/> 
SELECT ?pol ?lead TEXT(?c) SCORE(?c) WHERE { 
  ?pol fb:people.person.profession fb:m.0fj9f . 
  ?pol <in-context> ?c . 
  ?c <in-context> audience .
  ?lead <in-context> ?c . 
  ?lead fb:people.person.profession fb:m.05hmbp4 . 
  FILTER(?pol != ?lead) 
} ORDER BY DESC(SCORE(?c))

With typo ?audience instead of audience and missing selects I can produce a segfault:

PREFIX fb: <http://rdf.freebase.com/ns/> 
SELECT ?pol ?lead  WHERE { 
  ?pol fb:people.person.profession fb:m.0fj9f . 
  ?pol <in-context> ?c . 
  ?c <in-context> ?audience .
  ?lead <in-context> ?c . 
  ?lead fb:people.person.profession fb:m.05hmbp4 . 
  FILTER(?pol != ?lead) 
} 

Fix this after paper dealine!
