currTotalPixels is 0 in function regionMerge giving rise to core dumped when I run the main.cpp

[manketon]

I run the official demo, but there is a core-dumped.
int seedTotalPixels = pixelsInArea[seedSegment-1];
When seedSegment is 0, core dump with OpenCV 3.3.1

       change:

float rat = nextTotalPixels/currTotalPixels;

to:

        float rat;
        if(currTotalPixels==0)
        {
            rat = 2;
        } else
        {
            rat = nextTotalPixels/currTotalPixels;
        }

       change:

float rat = nextTotalPixels/currTotalPixels;

to:

        float rat;
        if(currTotalPixels==0)
        {
            rat = 2;
        } else
        {
            rat = nextTotalPixels/currTotalPixels;
        }

e... still can't work
