After fixing that error, the mainline does not segfault, the 4.0 branch still
does.

Reducing.

------- Comment #4 from pinskia at gcc dot gnu dot org  2005-10-07 02:16 -------
I am starting to think this is a front-end bug.  Removing all lines begining
with ^# "fixes" the ICE.

This looks like another "pragma interface" bug.

I am starting to think this is a dup of bug 22252 because of the diagnostic we
get.

Adding those patches into gcc-4.0.2 seems to resolve the problem.

Confirmed, reduced testcase:
typedef __SIZE_TYPE__ size_t;
struct Allocator { };
template<class T> struct  Ptr {     ~Ptr();     T *ptr_;  };
template<class T> struct ConstPtr : private Ptr<T> {     ConstPtr(const Ptr<T>
&p);  };
template<class T> Ptr<T>::~Ptr() {     delete ptr_;  }
#pragma interface
struct  AttributeDefinitionList {     ConstPtr<AttributeDefinitionList> prev_; 
};
struct  Dtd {     Ptr<AttributeDefinitionList> implicitElementAttributeDef_; 
};
struct  EndElementEvent {     void *operator new(size_t sz, Allocator &alloc); 
   EndElementEvent(const ConstPtr<Dtd> &);  };
struct  ArcProcessor {     void processEndElement(Allocator &);     Ptr<Dtd>
metaDtd_;   };
void ArcProcessor::processEndElement(Allocator &alloc) {     new (alloc)
EndElementEvent( metaDtd_);   }

------- Comment #9 from reichelt at gcc dot gnu dot org  2005-10-17 23:54 -------
Shorter testcase (ICEs with -O):

===============================================================
#pragma interface
template<typename T> struct A { T *p; ~A() { delete p; } };
template<typename T> struct B : A<T> { B(const A<T>&); };
struct C { B<C> b; C(const B<C>&); };
void foo() { new C(A<C>()); }
===============================================================
