out-of-range memory read

[dolphin-li]

GCoptimization.cpp, DataCostFnSparse::search(), line 1818: const SparseDataCost* mid = (const SparseDataCost*)((((size_t)L+(size_t)R) >> 1) & cDataCostPtrMask); It is possible that mid < L, causing out-of-range memory read. As a result, random crashes may occur under some OS environments, e.g., IOS/Android.
