>Description:
Compiler core dumps on attached code.  I originally
encountered the problem with 3.1; after upgrading to
3.2.2, it is still present.

Compiler output:

Re: c++/9708: Core dump from compiler

[bangerth]

Synopsis: Core dump from compiler

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Fri Feb 14 22:01:55 2003
State-Changed-Why:
    Reduced, this code looks like this:
    ---------------------------
    template <unsigned int N>
    char* begin(char (&a) [N] );
    
    template <unsigned int N>
    unsigned int size(char (&) [N] );
    
    void foo(char *);
    
    void bar()
    {
      char s[] = { 'a', 'b', 'c' } ;
      char d[ size( s ) ] ;
      foo(begin(d)) ;
    }
    ----------------------------
    This ICEs all compilers since at least 2.95. 3.4 presently
    gives this message:
    tmp/g> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c y.cc
    y.cc: In function `char* begin(char (&)[N])':
    y.cc:2: error: variable-size type declared outside of any function
    y.cc: In function `void bar()':
    y.cc:13: internal compiler error: Segmentation fault
