I maybe made a bit of progress.
This "Uninitialised value was created by a heap allocation" (wiringpi_gpio.cpp) seems to be related to the part
in the updateProperties() function where you test for NULL:

if (InputDigitalLP[i]->lp != NULL)
if (OutputDigitalSP[i]->sp != NULL)
My thought was that "InputDigitalLP->lp" and "OutputDigitalSP->sp" needs to be initialized with something...
So I assigned NULL to it right after its creation in the "WiringPiGPIO::WiringPiGPIO()" constructor:
    for (int i = 0; i < NUMBER_OF_PINS; i++)
        InputDigitalLP[i] = new ILightVectorProperty;
        OutputDigitalSP[i] = new ISwitchVectorProperty;
                // added
                InputDigitalLP[i]->lp = NULL;
                OutputDigitalSP[i]->sp = NULL;
    OutputPWMNP = new INumberVectorProperty;


I really dont know If this is the right way to do it but a first tests with the new code show normal behaviour of the driver (compiled with gcc-6.x).
I can set gpio's, switch them, and save them successfully B).
I will report back if there is any new fail.
