The following code snippet causes an ICE on x86_64-unknown-linux-gnu
when compiled with "-fschedule-insns -fstack-protector-all".
This happens since 4.1.0 when -fstack-protector-all was introduced.

=========================================================================
int foo(int i)
{
    i /= i+1;
    return 0;
}
=========================================================================

------- Comment #1 from pinskia at gcc dot gnu dot org  2006-04-03 15:06 -------
This is the normal problem of using specific registers for multiplication on
x86 and x86_64 so running out of registers is easy :).

------- Comment #3 from reichelt at gcc dot gnu dot org  2009-11-14 17:07 -------
The code compiles without ICE on trunk since at least 2009-09-17.
So lets close it as fixed.
