The following (probably invalid) code snippet triggers an ICE on mainline:
===========================================
struct A
{
operator int();
};
template <typename... T> struct B : A
{
using A::operator T;
};
B<int> b;
===========================================
bug.cc: In instantiation of 'B<int>':
bug.cc:11: instantiated from here
bug.cc:8: internal compiler error: in dependent_type_p, at cp/pt.c:15327
Please submit a full bug report, [etc.]
Another code snippet that ICE's in the same place:
===========================================
template<typename... T> struct A
{
int i __attribute__((aligned(__alignof(T))));
};
A<int> a;
===========================================
bug.cc: In instantiation of 'A<int>':
bug.cc:6: instantiated from here
bug.cc:3: internal compiler error: in dependent_type_p, at cp/pt.c:15327
Please submit a full bug report, [etc.]
