optimization/9786: [3.2/3.3/3.4 regression] Ice in fixup_abnormal_edges with -fnon-call-exceptions -O2

[Nick Rasmussen]

I've already traced down what triggered the ICE:

http://gcc.gnu.org/ml/gcc-bugs/2003-03/msg00025.html

And got a reply from Jan Hubicka:

http://gcc.gnu.org/ml/gcc-bugs/2003-03/msg00034.html

It looks like it just didn't get attached to the gnats entry.
