 Yes.

 Right, but this is accidentally, or at best an extension of these 
 compilers. I think in prior versions of gcc this was more by chance.

 Hi,
 
 Thank you very much for your prompt response.  Is the restriction on paranthesis 
 use conforms to the C++ standards?
 
 Note that this code compiles and works as intended on other compilers.
 
 Sincerely,

>Description:

class foo
  {
    public:
        foo( void ){};
        ~foo( void ){};
        foo& operator&=( const foo& f ){ return *this; };

  };


void func( foo* p )
  {

    typedef foo& (foo::*MEM_FUNC_PTR)( const foo& );

    MEM_FUNC_PTR mfptr = &( foo::operator&= );

    (p->*mfptr)( *p );
  }

>How-To-Repeat:
Place the above code in a file, say test_pgm.cc.
Compile it with g++ -c test_pgm.cc (g++ version 3.2 on Sparc
Solaris and on Linux).  The output is:

 /local8/bin/gcc32/bin/g++ test_pgm.cc
test_pgm.cc: In function `void func(foo*)':
test_pgm.cc:17: Internal compiler error in resolve_offset_ref, at cp/init.c:
