Jan Steemann f3107bc25f Merge branch 'devel' of https://github.com/arangodb/arangodb into aql-operators 2016-02-10 11:34:40 +01:00
jsteemann a02e2b563f fixed issue #1707: 2.8.1 crashes 
the crash was due to a required variable being removed from the execution plan.
this happened when there were multiple execution plans, and a certain transformation
was made in one of them. the transformation modified an element that was shared by
all plans, but it should have made a copy so only the current plan is affected
