BUG in G++ 1.32.0 - c++ get segmentation violation

I thought that I would try something tricky and see if I could
redefine the sizeof operator. I ran the following code thru
G++ 1.32.0 and it got a segmentation violation in c++.
There are two issues here. First, it's obvious that the segmentation
violation shouldn't occur. Second, I think that allowing the sizeof
operator to be redefined would be a nice feature, and consistant
with the general philosophy of letting all operators be redefined.
What does cfront (1.2/2.0) do with this code?
class test {
public:
virtual operator sizeof();
};
