Issue :
-------
This seems for some platform -(LONGLONG_MIN) is
not flagged as out of range.

Fix:
----
Fix is backported from mysql-5.6 bug 14314156.
Fixed by adding an explicit test for this value in
Item_func_neg::int_op().

sql/item_func.cc:
  For some platforms we need special handling of
  LONGLONG_MIN to guarantee overflow.
