Confirmed, here is the reduced self testing testcase:
void abort (void);
int mid_wts[2][2]={};
int in_pats[2]={};
int do_mid_forward()
{
  int sum;
  int     neurode, i;
  for (neurode=0;neurode<2; neurode++)
  {
    sum = 0;
    for (i=0; i<2; i++)
      sum += mid_wts[neurode][i]*in_pats[i];
    sum += 1;
  }
  return sum;
}
int main()
{
  if (do_mid_forward(0) != 1)
    abort ();
  return 0;
}
