Setter from other class

I have a class called "StatusInformation", where I want to set the variable _status to true/false, but I am getting only "segmentation fault". I think, that the _status doesn't exist, becouse I call it from the other class. Anybody know how to prevent this error?

StatusInformation.cpp

void StatusInformation::SetClientConnectStatus(bool status)
{
    _status = status;
}

StatusInformation.h

class StatusInformation
{
private:

    bool _status = false;

public:

    void SetClientConnectStatus(bool status);
};

CallerClass.cpp

_statusInformation = new StatusInformation();

_statusInformation->SetClientConnectStatus(true);

CallerClass.h

StatusInformation *_statusInformation;

EDIT : That link to your code is just giving me code that is missing ArduinoProtocol.

For me, this compiles with 2 warnings about non static data-member initializers, and then runs fine. I really do not believe the segmentation fault can come from this code. The only thing that could cause that would be if 

_statusInformation = new StatusInformation();

Failed and returned 0, making your pointer a NULL pointer. Causing:

_statusInformation->SetClientConnectStatus(true);

To be equivalent to :

NULL->SetClientConnectStatus(true);

But that could only happen if you chose to use a no-throw new. Which you much specify. So realistically, the only thing in that code that could make you segmentation fault, cannot happen. Worst case an std::bad_alloc will be thrown.
