[Bug middle-end/26717] [4.2 Regression] gfortran: ICE at tree-complex.c:133 with -O -ffast-math in LAPACK,

[pinskia at gcc dot gnu dot org]

------- Comment #3 from pinskia at gcc dot gnu dot org  2006-03-16 16:21 -------
Reduced C testcase:
_Complex float f(_Complex float a, _Complex float b)
{
  _Complex float c = a/a;
  return c/ b;
}
------
The problem is that fold is folding a/a to 1.0 but not the complex version.
