 Yup, it is fixed.  You can close it.
 
 Thanks again,

 What can I say -- I reduced and filed 10471, only to find out shortly 
 after that almost exactly the same bug had already been filed a couple of 
 hours earlier. The bug only existed about a day, and we now have 3 reports 
 about it...
 
 Can you ping me when you find that it is indeed fixed for your code? I'll 
 close the report then, if you want.

 That test case indeed fails with my current 3.3.
 I'll update again and retry.  Too bad I wasted a whole evening
 condensing that test case while it was already fixed :/.
 But I'm happy it is fixed already anyway.
 
 Thanks!

    This is isomorph (there is a continuous deformation) from your

    which I think is the same as 10471. Mark fixed that sometime
    this night, and I don't see it in a 3.3 checked out
    this morning Texas time. I see it in 3.4 from yesterday.
    From when is your version? I bet you should just update
    and try again :-) Would you mind?

>Description:
After updating my CVS source tree at 20030424,
while the last update was from around 20030404,
I ran into a new ICE.

This is a regression, all previous versions compile
this fine, as did version 3.3 20030404.

Please submit a full bug report,

>How-To-Repeat:
Compile the following code snippet:


template<typename _Tp, typename _Alloc>
  struct A
  {
    typedef typename _Alloc::template rebind<_Tp>::other allocator_type;
    A(allocator_type const& __a = allocator_type()) { }
  };

template<typename T>
  struct B
  {
    template <typename T1>
      struct rebind
      {
        typedef B<T1> other;
      };
    ~B() { }
  };

A<int, B<char>::rebind<int>::other> x;
>Fix:
Among others, removing the "~B() { }" helps.
