Bug#16359402 CRASH WITH AGGREGATES: ASSERTION FAILED: N < M_SIZE

Browse source 
Post push fix:
setup_ref_array() now uses n_sum_items to determine size of ref_pointer_array.
The problem was that n_sum_items kept growing, it wasn't reset for each query.

A similar memory leak was fixed with the patch for:
Bug 14683676 ENDLESS MEMORY CONSUMPTION IN SETUP_REF_ARRAY WITH MAX IN SUBQUERY
