![]() Thus the test case with initialization uses pre-initialized memory block with random data which is copied to target buffer. The typical memory block usage usually is not byte access, but some more bulky, like mem copy, integer, long, etc i.e. The data initialization is done by doing memcpy. In test cases with out memory initialization, the memory pointer addresses are summed and printed on stderr, so that compiler would optimize the allocations because of no further usage.
