Hello. I am trying to call a function that, after executing get a position in a variable:

PHP Code:

cell_t L4D2_GetRandomSpawnPosition(IPluginContext *pContext, const cell_t *params)
{
    if (g_pZombieManager == NULL)
    {
        return pContext->ThrowNativeError("ZombieManager unsupported or not available; file a bug report");
    }

    static ICallWrapper *pWrapper = NULL;

    if (!pWrapper)
    {
        REGISTER_NATIVE_ADDR("GetRandomSpawnPosition", 
            PassInfo pass[4]; \
            pass[0].flags = PASSFLAG_BYVAL; \
            pass[0].size = sizeof(ZombieClassType); \
            pass[0].type = PassType_Basic; \
            pass[1].flags = PASSFLAG_BYVAL; \
            pass[1].size = sizeof(int); \
            pass[1].type = PassType_Basic; \
            pass[2].flags = PASSFLAG_BYVAL; \
            pass[2].size = sizeof(CBaseEntity *); \
            pass[2].type = PassType_Basic; \
            pass[3].flags = PASSFLAG_BYVAL; \
            pass[3].size = sizeof(Vector*); \
            pass[3].type = PassType_Basic; \
            pWrapper = g_pBinTools->CreateCall(addr, CallConv_ThisCall, NULL, pass, 4));
    }

    int client = params[3];
    CBaseEntity * pClient = NULL;
    if (client != -1)
    {
        pClient = UTIL_GetCBaseEntity(client, true);
        if(pClient == NULL) 
        {
            return pContext->ThrowNativeError("Invalid client entity");        
        }
    }

    Vector vector;
    vector[0] = sp_ctof(0.0);
    vector[1] = sp_ctof(0.0);
    vector[2] = sp_ctof(0.0);

    unsigned char vstk[ sizeof(void*) + sizeof(ZombieClassType) + sizeof(int) + sizeof(CBaseEntity *) + sizeof(Vector*) ];
    unsigned char *vptr = vstk;

    *(void **)vptr = g_pZombieManager;
    vptr += sizeof(void *);
    
    *(cell_t*)vptr = params[1];
    vptr += sizeof(ZombieClassType);

    *(int *)vptr = params[2];
    vptr += sizeof(int *);

    *(CBaseEntity **)vptr = pClient;
    vptr += sizeof(CBaseEntity *);

    *(Vector**)vptr = &vector;

    pWrapper->Execute(vstk, NULL);

    const void *buffer = (const unsigned char *)vstk + pWrapper->GetParamInfo(3)->offset;

    Vector *v = NULL;
    v = *(Vector**)buffer;

    cell_t* addr;
    pContext->LocalToPhysAddr(params[4], &addr);

    addr[0]=sp_ftoc(v->x);
    addr[1]=sp_ftoc(v->y);
    addr[2]=sp_ftoc(v->z);
    return 0;
} 


It works in linux, but in windows I get a server crash on pWrapper->Execute(vstk, NULL);... How can I assign a different solution so that after the call, the function returns an updated variable (like for example VENCODE_FLAG_COPYBACK in sdktools)?
