This is fixed, even if I disable VRP / jump-threading and substitute the info
from comment #3 in the code:

double MyFunc2 (int size)
{
  int len = size + 1;
  double Data[16] = {0};
if (len > 3)
  ;
else if (len > 0)
  ;
else
  return 0;

  for (int i=0; i<len; i++)
    Data[i] = Data[i]>=0 ? Data[i] : -Data[i];

  return Data[1];
}
