Synopsis: ICE with segfault on include inside namespace

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Tue Dec 17 16:18:37 2002
State-Changed-Why:
    Confirmed. It's even a regression, since this worked without
    an ICE with the 2001-12-01 snapshot.
    
    However, the code is not legal, and there are lots of
    error messages before that, so the user clearly sees
    what is going on and the ICE is not so bad here. I thus
    reduce the priority of this report.
    
    Thanks anyway for reporting this
      Wolfgang
