Subject: Bug 793277 Use after free in main()

The problem is the scope of the return value from data.get_servers()
which is a std::set of Quarks

The temporary used for this value goes out of scope at the end of
the statement containing it - within the for loop control
statement - it is not in scope in the loop body.

The result is that later dereferencing the iterator on line 1158
accesses memory which has been returned to the heap.
