State-Changed-Why:
    Fixed in gcc 3.1.
    
    I can reproduce the PR with gcc 3.1 20020125 (the compiler uses more than
    500 MB and compiles forever - I killed it after a couple of minutes).
    
    With gcc 3.1 - 3.2.3 the compiler uses less than 70 MB and takes less than
    10s on my comuter.
