internal compiler error

[Mark Johnstone]

Hello all,

The following simple program generates an internal compiler error in
both 1.0.1 and the 980115 snapshot:

#include <stddef.h>	// need this for offsetof macro, NULL & size_t defines

class CapData;

template <class T_Type> class NewBlocks
{
  private:

    T_Type * next;
    static const char * NewBlocks<T_Type>::static_tag_string;

  public:

  // removed for clarity
    
};

class CapData : public NewBlocks<CapData>
{
  private:
    CapData( const CapData& cd )  {}		// block copy constructor
    CapData& operator=( const CapData& cd)  { return *this; }
    CapData() : next(NULL), shape_id(0), cap_val(0) {}

    int shape_id;
    float cap_val;
    CapData * next;

  public:
    float  & asgnCapVal()	{ return cap_val; }
    float capVal() const	{ return cap_val; }			
    int   id()     const	{ return shape_id;}
};

int  main( int argc, char * argv[] )
{

    return 0;
}


Here is the message:
