State-Changed-Why:
    Since two of us can't reproduce this, it must be something
    in your local installation. There are two ways how you can
    do anything about it:
    - try bootstrapping gcc3.2.1 on your machine
    - try to get help from the debian people from which you
      got the package.
    
    Sorry

 With gcc 3.0 and later identifiers from the standard library are in
 namespace std and no longer in namespace ::. This means that you
 have to qualify things like cout with std::. If someone can reproduce
 this it might well turn out that the ICE also happens with legal code.

 the install was done via debian packages (dselect from the unstable
 branch to be specific). simple c programs compile, but compiling the
 kernel results in a segmentation fault as well (i have not submitted a
 bug report for that yet.) this program fails every compile. i dont know
 what else to do, i have tried purging and reinstalling certain packages
 (and shaking my fists at the monitor) but i do not know enough to do any
 serious debugging. let me know if there is anything i could try (to help
 debugging).

 what do you mean when you say that the code is illegal?
