g++ bug? (Internal compiler error)

[Marc Guiot du Doignon <guiot at nmu dot alcatel dot fr>]

Hi,

The program below gives an error with g++ 2.95.2 and newer. (not with
aCC 1.21)
I also try it with the online compilation.

$ cat testGcc.cc

template <class T, void (T::*FOO)()>
class info
{
  public :
    info(){}
    void operator()(T* t)
    {
      (t->*FOO)();
    }
};

class toto
{
  public :
    virtual void foo() = 0;
    info<toto, &toto::foo> inf;
};

without virtual it work well.


$ gcc -v --save-temps -c testGcc.cc
