When running :tier1 hs tests, the following issue has been reported with ubsan enabled (configure flag --enable-ubsan) the following issue is reported .
Reason is that gtest forces a call void* no_data_copy = GuardedMemory::wrap_copy(no_data, 0); with 0 length . This leads to a special case for memcpy .
