[rguenth at gcc dot gnu dot org]

------- Comment #5 from rguenth at gcc dot gnu dot org  2008-02-04 14:57 -------
Executable testcase:

extern double fabs(double);
extern void abort(void);
void __attribute__((noinline)) foo(double x)
{
  if (fabs (x) != 0.0)
    abort ();
}
int main ()
{
  foo(-0.0);
  return 0;
}
