And even all this may not help.
You can study the standard, provide a testcase, show
a regression with respect to releases, keep track of any
new snapshot, and still not get any response (let alone
useful ones).

I know, the developers are all volunteer, and I am really
grateful for all the good work they do. However, I did not
get any response for a couple of bug reports I sent one month
ago. Seeing so many vague bug reports being given detailed
answers, I felt like making a scene of jealousy ;)

  [Almost crying]
  I take any possible care to provide good reports,
  why you guys seem not to care?

Seriously, the following report (updated to the latest
snapshot) shows a problem that doesn't allow me to
fully test any snapshot on my application since release 1.0.2.
Please, at least tell me whether I have misread the standard.

Reading 12.4 I understand that the fragment

  void foo(I* p)
  {
    p->I::~I();
  }

should be ok whatever type I is.
(Point 15 in 12.4 specifies that it works also for scalar types,
e.g., typedef int I.)

However, if I define

    typedef C I;

for C anything
(e.g.

   class C {
   public:
     int i;
   };

see below) any snapshots since April 18 gives

/u/local/bin/g++ -c -Wall bugrep1.cc
bugrep1.cc: In function `void foo(class I *)':
bugrep1.cc:53: qualified type `C' does not match destructor name `~I'

Note that all the egcs releases do not have this problem.
