 Line-numbered input is:
 ========================================
      1  void *malloc(unsigned int size);
      2  template<int> void foo() {
      3    malloc (sizeof (int));
      4  }
      5  template void foo<1>();
      6 
 
 ========================================
 
 
 Diagnostic output follows, from the last compiler tested:
 input: In function `void foo()':
 input:3: internal compiler error: Segmentation fault
 Please submit a full bug report,
 with preprocessed source if appropriate.
 See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
 
 Compiler output follows, from the last compiler tested:
         .file   "input"
 
 So, 99% sure that this is caused by the new parser.

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-By: bangerth
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:

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