That was the plan. Copy Cell member_data_cell to dest. All of it, of course. No reason to complain IMHO.
Value.cc:923:23: note: explicitly cast the pointer to silence this warning
         memcpy(dest, member_data_cell, sizeof(Cell));
1 warning generated.
mv -f .deps/apl-Value.Tpo .deps/apl-Value.Po
