lvgl / lv_demos

The function rnd_next in the lv_demo_benchmark causes a floating point exception in line 1007 in case both input arguments are equal.

static int32_t rnd_next(int32_t min, int32_t max)
{
    if(min > max) {
        int32_t t = min;
        min = max;
        max = t;
    }

    int32_t d = max - min;
    int32_t r = (rnd_map[rnd_act] % d) + min;  // Exception here

    rnd_act++;
    if(rnd_act >= RND_NUM) rnd_act = 0;

    return r;

}

This case is handles here:

lv_demos/src/lv_demo_benchmark/lv_demo_benchmark.c

Lines 1004 to 1005 in 1c0552b

    
           if(min == max) 
        
               return min;

Oh I'm sorry, I was still checking out v8.0.1... silly me.
