How to setup a data breakpoint on a reference

I have a 64 bit reference to an object where the low order 32 bits of the reference are getting overwritten with 0xFFFFFFFF. I can't figure out how to set a data breakpoint on the bytes for the reference itself because the watch window gives me no way to acquire the address of the reference.

I see two solutions (if I correctly understood the problem):

• change the reference to a pointer;
• add a dummy variable in front of your reference - see the code below - and set the break-point to its address.

class object_t
{
public:
  int i;
};

class test_t
{
public:
  int64_t dummy {};
  object_t& ro;
  test_t( object_t& aro ) : ro { aro } {}
};

int main()
{
  object_t obj;
  test_t c { obj };

  // without dummy
  int64_t* p = (int64_t*)&c;
  *(int32_t*)p = 0xffffffff; // simulates memory corruption
  c.ro.i = 0; // exception

  // with dummy
  int64_t* p = (int64_t*)&c;
  *(int32_t*)p = 0xffffffff; // will break 

  return 0;
}
