--- Comment #1 from jakub at gcc dot gnu dot org  2009-12-01 08:19 ---
Simplified testcase without the undefined signed underflow:
void
foo (int x)
{
  struct S { int s; } d = { 1 };
  unsigned int e = 1;
  if (x)
e = x  d.s;
  else
for (e = 0; e = 3; e--)
  ;
  e++;
}

The problem starts in *.cddce1, before that we have:
  # e_2 = PHI e_9(6), e_1(8)
  # DEBUG e = e_2
  # DEBUG e = e_2 + 1
but after that only:
bb 6:
  # DEBUG e = e_1
  # DEBUG e = e_1 + 1
where e_1 is defined only in one of the predecessors of bb 6.
