bug with enum, templates and typedef

the following piece of code crash the compiler:

miniussi@nice > server : m truc.cpp
struct  S1 { enum E { v = 1}; };   
typedef S1::E TD;
template <TD val> struct S2 {};

miniussi@nice > server : ~/egcs/solaris/112p2/bin/g++ -c truc.cpp -v

The following variants seems to work fine:

struct  S1 { enum E { v = 1}; };   
typedef S1::E TD;
template <S1::E val> struct S2 {};
-----------------------
enum S1E {v = 1};

struct  S1 { 
  typedef S1E E;//enum E { v = 1}; 
};   

typedef S1::E TD;

template <TD val> struct S2 {};
-----------------------
struct  S1 { typedef int E; };
typedef S1::E TD;
template <TD val> struct S2 {};

Is it fixed in the last version ?

Thanks,

Alain
