Summary: Stack pointer lost in loop

Initial Comment:
void bug (float f)
{
  long buf[50];
  unsigned char i;
  i=10;
    do {
      buf[i]=f;
    } while (--i);
}

void main()
{
  bug(1.414);
}

At the "while (--i)" point the stack pointer changes 
downward by 4 bytes at each iteration resulting in loss of 
reference to i.  A smaller buf (less than 128 bytes) works.
