------- Comment #2 from redi at gcc dot gnu dot org 2010-07-05 23:26 -------
unpreprocessed source (because preprocessed boost source is so dependent on
compiler version it often won't compile with other versions)
#include <boost/intrusive/list.hpp>
struct A : public boost::intrusive::list_base_hook<> {
virtual ~A() {}
};
template<class X>
struct D : A {
X x;
D(const X& x) : x(x) {}
};
typedef boost::intrusive::list<A> A_list;
struct data_holder {
A_list a;
template<class C>
static void delete_disposer(C* c){
delete c;
}
template<class X>
D<X>* insert(const X& x){
D<X> *t = new D<X>(x);
a.push_back(*t);
return t;
}
template<class X>
void remove(D<X>* t){
A_list::iterator it = A_list::s_iterator_to(*t);
a.erase_and_dispose(it, delete_disposer<A>);
}
};
int main() {
data_holder data;
D<int> *i = data.insert(10);
data.remove(i);
return 0;
}
This ICEs with Boost 1.39 or current Boost trunk, using any of 4.5.1, 4.6.0 or
Fedora 4.4.3

ICE is always at the same place

------- Comment #4 from chtz at informatik dot uni-bremen dot de 2010-07-06 22:06 -------
I found two possible work-arounds:
either replace:
> template<class X>
> void remove(D<X>* t){
> A_list::iterator it = A_list::s_iterator_to(*t);
> a.erase_and_dispose(it, delete_disposer<A>);
> }
by:
template<class X>
void remove(D<X>* t){
A_list::iterator it = A_list::s_iterator_to(*t), it2 = it;
++it2;
a.erase_and_dispose(it, it2, delete_disposer<A>);
}
Or, what also works, is replacing delete_disposer<A> by a non-template version:
void delete_A(A* a){ delete a; }

This needs a C++ FE maintainer to take a look.
