[Bug tree-optimization/26757] [4.1 regression] ICE (Segmentation fault) building 3ddesktop source

["ferdinandw+gcc at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #5 from ferdinandw+gcc at gmail dot com  2006-03-26 02:19 -------
Here's a reduced version that gives me an ICE on FC5's gcc 4.1.0 with:
g++ -O -c 3ddeskd.cpp

=====================================

class Config {
public:

    int texture_size;
    int bg_size;
    int autoacquire;

};

class Face {
public:

    void load_texture_data (int texture_size) {

        extern Config *cfg;

        cfg->bg_size++;
    }

};


class FaceSet {
private:

    Face faces;

public:

    void load_texture_data (int size) { 
        faces.load_texture_data(size);
    };

};


Config *cfg;
FaceSet *face_set;

void load_background_image(void) 
{
    cfg->bg_size++;

    extern Config *cfg;

    cfg->autoacquire++;

}


void 
humbug ()
{
    if (cfg->autoacquire)
    face_set->load_texture_data(cfg->texture_size);

}

=====================================
