--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I meant in the first loop.
But we handle:
int b, c, e;

long
foo (int x, int y)
{
  long h = 0;
  for (b = 0; b < x; b++)
    for (c = 0; c < y; c++)
      if (e)
        h = 1;
  return h + 4;
}
correctly, it is only as soon as one of those loops turns into endless loop:
int b, c, e;

long
foo (int x, int y)
{
  long h = 0;
  for (b = 0; b < x; b++)
    for (c = 0; c < y;)
      if (e)
        h = 1;
  return h + 4;
}
that we lose track.  But, if it is only for endless loops, probably nothing to
worry about, the finite loops are much more important.
