Starting from moment when the problematic param was added.

$ cat ice.c
void a ()
{
  volatile int b;
  for (;; b)
    ;
}

gcc -Os --param gcse-cost-distance-ratio=2147483647 -c ice.c -c
ice.c: In function ‘a’:
ice.c:6:1: internal compiler error: in want_to_gcse_p, at gcse.c:804
 }

I've got patch for that.
