Subject:	GCC Bug

If you try to compile the following code fragment that uses templates, it generates bad assembly code if the -gcoff switch is used.  What's weird is if I get rid of the virtual keyword on the destructor, it assembles fine.  Any ideas?

FAILS:  c4x-g++ -c -gcoff test.cc
PASSES: c4x-g++ -c test.cc


prompt> c4x-g++ -c -g test2.cc
/tmp/ccMHRRGe.s: Assembler messages:
/tmp/ccMHRRGe.s:11: Error: Rest of line ignored. First ignored character is `<'.
prompt> 


Offending assembly line:
        .sdef   __vptr$d<5>
        

test.cc:
template <int Count>
class d
{
public:
  d() 
  { 
        myInt = Count;
  }
  int myInt;
  virtual ~d() {}
};

volatile d<5> instD;
