State-Changed-Why:
    Confirmed with 3.2, but already fixed in 3.3 and mainline.
    Here's a smaller example:
    -----------------------------
    typedef struct  {
        struct Y * dummy;
    } X;
    
    void f1(struct Y *A1);
    void f2(double value);
    struct Y y;
    
    float foo(float A_r) {
        f2(A_r);
        f1(&y);
        undeclared();
    }
    -------------------------
    With 3.2.2 I get
    /x> /home/bangerth/bin/gcc-3.2.2-pre/bin/gcc -c -O2 colors-preprocessed.c
    colors-preprocessed.c: In function `foo':
    colors-preprocessed.c:13: internal error: Segmentation fault
    Please submit a full bug report,
    
    It works with 3.0, so this is a regression. However, as
    said, this is already fixed on newer branches.
