------- Comment #1 from pinskia at gcc dot gnu dot org  2008-12-02 00:11 -------
Here is a shorter testcase:
void _ov_64_seek_lap (void)
{
  _Bool x1, x2, x3;
  unsigned ltmp_3978_7;
  unsigned ltmp_3978_7__PHI_TEMPORARY;
  unsigned ltmp_4011_7__PHI_TEMPORARY;
  unsigned ltmp_4012_7;
  signed ltmp_4011_7;

  if (!x1 || !x2)
    while (1) ;

  if (x3)
    ltmp_3978_7__PHI_TEMPORARY = 0xffffff7e;
  else
    ltmp_3978_7__PHI_TEMPORARY = 1;

  ltmp_3978_7 = ltmp_3978_7__PHI_TEMPORARY;
  ltmp_4011_7__PHI_TEMPORARY = 0xffffffff;
  ltmp_4011_7 = ltmp_4011_7__PHI_TEMPORARY;
  ltmp_4012_7 = ltmp_4011_7 >> ltmp_3978_7;
}
