    typedef struct {
        int x;
    } A;

    class B: public A {
        int y;
    };

Notes:
    This is nasty (probably invalid) code, but it works
    under -ggdb, and probably shouldn't segfault anyway.

Release:
3.1

 GCC crashes at least since 2.95.x on the code.
 This affects also 3.3 branch and mainline as of 2003-05-06.
 
 BTW, the code looks legal to me.

This also fails in 3.2.2 and 3.2.3.

Most likely the same fix for bug 11473, fixed this bug.  I will submit a
testcase when I get 
cvs access.
