Subject: Re:  crashes in on kopete build (KDE's kdenetwork)

Maybe a good test would be, instead of compiling only test cases to try 
to recompile KDE with 4.0 once??

I can't do it here, with recent snapshot from CVS, because it causes 
strange problems with other compiler versions (namely 3.3 and 2.95). And 
I have no idea how to compile it so it won't interfere with them.

I can confirm this, I started to reduce this, I have it done to about 9000 lines.

Confirmed, here is the reduced testcase (someone can most likely reduce this a little more):
 struct FieldListIterator
 {
   struct t {struct t *next; };
   t *node;
   FieldListIterator();
   FieldListIterator (const FieldListIterator&);
   FieldListIterator operator++(int){
 FieldListIterator  tmp = *this;
 node = node->next;
 return tmp;
    }
   FieldListIterator &operator++(){
 node = node->next;
 return *this;
    }
 };
 struct FieldList
 {
   virtual ~FieldList();
   FieldListIterator find( FieldListIterator &it);
 };
void take()
{
 FieldList contactListFields;
 for ( FieldListIterator it;
    1;
    it = contactListFields.find( ++it))
 {
 }
}

: Search converges between 2004-06-20-trunk (#469) and 2004-06-22-trunk (#470).

Here's something smaller:

    A();

Hmm, this seems wrong:

Here is the full tree dump (having the two constructors of A being empty otherwise we don't get the 
dump as it is STATEMENT_LIST which we should be dumping):
<<< Unknown tree: for_stmt


  <<cleanup_point a = *(struct A &) (struct A *) &TARGET_EXPR <D.1582, <<< Unknown tree: 
aggr_init_expr
