    Description

      As I built release/lithium on my windows box, I received a warning message complaining dereferencing of empty optional. Following the call stack, the violator is in Value+Dump.cc, l170,

      offset = *valueToOffset(dstPtr);

      Compared with MacOS/Clang, the empty optional yields 0.
