How to mock a method with optional parameter in Google Mock? For example: I try this, but it does not work:

template <typename T>
class A
{ 
public:
    virtual void set_enable(const int test, const bool enabled = true ) const;
};

template <typename T>
class MockA : public A<T>
{
    MOCK_CONST_METHOD2_T( set_enable, void(const int test, const bool enabled ) );
    void set_enable(const int test /*, const bool enabled = true*/ ) const
    {
        set_enable( test, true);
    }
};

Then call:

MockA mockA;
EXPECT_CALL(mockA, set_enable(_,true)).Times(Exactly(1));

When I run test, it show "Segmentation fault"
