GMOCK Exception UntypedDescribeUninterestingCall read access violation

I have a mock class

class AMock : public InterfaceA
{
public:
    MOCK_METHOD2(afuncProxy, void(int, uint8_t*));
    void afunc(int i, std::unique_ptr<B> b)
    {
        auto data = b->getData();
        b.release();
        afuncProxy(i, data);
    }
};

In my code I create class like below:

AMock mymock;

In test case :

    auto inData  = new uint8_t[5] { 0, 1, 2, 3, 4 };
    auto outData = new uint8_t[5] { 5, 6, 7, 8, 2 };
EXPECT_CALL(mymock, afuncProxy(_, _)).Times(1).WillOnce(SaveArg<1>(&outData));

Where

ACTION_TEMPLATE(SaveArg, HAS_1_TEMPLATE_PARAMS(int, k), AND_1_VALUE_PARAMS(destination))
{
    *destination = std::move(::std::tr1::get<k>(args));
}

I am able to get the data in outData variable but at the end of test case I get read access violation exception:

// Warns about the uninteresting call.
::std::stringstream ss;
this->UntypedDescribeUninterestingCall(untyped_args, &ss);

What is the issue?
