…e sometimes (#26933)
BitmapValue::write_to will get a string with size 1 for empty BitmapValue,
however the size 1 string will reinterpret to BitmapValue* back in
ColumnComplexType::insert: void insert(const Field& x) override {
const String& s = doris::vectorized::get<const String&>(x);
data.push_back(reinterpret_cast<const T>(s.c_str())); }
in data.push_back will goto BitmapValue copy constructor, as the _type is
not first member in BitmapValue, cause access to an unknown memory location.
