Memory leak calling .Net dll from C++ - c++

Question

I'm getting a memory leak when calling a .Net dll from C++ in the function below. I'm thinking it is with the SafeArray declaration but I don't know how else to release the memory besides SafeArrayDestroyDescriptor. What else am I missing?
VARIANT_BOOL SendPack(IDotNetDll* wb, WW_POLL pl)
{
HRESULT hr = 0;
VARIANT_BOOL bretval;
BYTE destination = pl.uDest;
BYTE raw[2];
raw[0] = pl.uAPI;
raw[1] = pl.uOpcode;
SAFEARRAY* bytes = NULL;
hr = SafeArrayAllocDescriptor(1, &bytes);
bytes->cbElements = sizeof(raw[0]);
bytes->rgsabound[0].cElements = sizeof(raw);
bytes->rgsabound[0].lLbound = 0;
bytes->pvData = raw;
bytes->fFeatures = FADF_AUTO | FADF_FIXEDSIZE;
wb->SendMessage(destination,(BYTE)4, bytes, VARIANT_FALSE,
200.0,&bretval);
SafeArrayDestroyDescriptor(bytes);
return bretval;
}
Edit:
I also tried this method using a variant
VARIANT_BOOL SendPacket(IDotNetDll* wb, WW_POLL pl)
{
HRESULT hr = 0;
VARIANT_BOOL bretval;
_variant_t var;
void * pArrayData = NULL;
var.vt = VT_ARRAY | VT_UI1;
SAFEARRAYBOUND rgsabound1[1];
rgsabound1[0].cElements = 5;
rgsabound1[0].lLbound = 0;
var.parray = SafeArrayCreate(VT_UI1, 1, rgsabound1);
BYTE destination = pl.uDest;
SafeArrayAccessData(var.parray, &pArrayData);
BYTE raw[5];
raw[0] = pl.uAPI;
raw[1] = pl.uOpcode;
raw[2] = pl.uPayLoad[0];
raw[3] = pl.uPayLoad[1];
raw[4] = pl.uPayLoad[2];
memcpy(pArrayData, raw, 5);
SafeArrayUnaccessData(var.parray);
//Send packet
wb->SendMessage(destination,
(BYTE)4,
var.parray,
VARIANT_FALSE,
200.0, &bretval);
var.Clear();
return bretval;
}
