Old Synopsis: ICE when casting in static member
New Synopsis: [3.4 regression] ICE in type_unknown_p when casting in static member

State-Changed-From-To: open->analyzed

State-Changed-When: Thu Feb 20 20:15:38 2003
State-Changed-Why:
    Confirmed. Here's a smaller snippit:
    -------------------
    void *malloc(unsigned int size);
    
    template<int> void foo() {
      malloc (sizeof (int));
    }
    
    template void foo<1>();
    --------------------------
    g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc
    x.cc: In function `void foo()':
    x.cc:5: internal compiler error: Segmentation fault
    
    
    This ICEs present mainline, and the regression was
    introduced between 2002-12-25 and 2003-01-05, i.e. 
    possibly with the new parser. 3.3 is ok.
    
    A backtrace shows this:
    #0  0x08104253 in type_unknown_p (exp=0x4017bf30)

    From there I don't know further, of course.
