[Bug c++/42713] [4.5 Regression] ICE - segfault in tsubst
------- Comment #3 from dodji at gcc dot gnu dot org 2010-01-14 14:39 -------
Here is a smaller reproducer:
template<class T>
struct S
{
};
template<class T>
struct S0
{
typedef T TT;
};
template<class U, class V>
struct super_struct : S0<V>
{
typedef S0<V> super;
};
template<class U, class V, class W>
struct S1 : super_struct<U, V>
{
typedef super_struct<U, V> super;
typedef typename super::super Super2;
typedef typename Super2::TT Super2TT;
void
foo()
{
S<Super2TT> s1;
}
};
template<class U, class V>
struct S2 : super_struct<U, V>
{
typedef super_struct<U, V> super;
typedef typename super::super Super2;
typedef typename Super2::TT Super2TT;
void
foo()
{
S<Super2TT> s1;
}
};
int
main()
{
S1<int, S<int>, int> s1;
s1.foo();
S2<int, S<int> > s2;
s2.foo();
}
