>Description:
While playing with c++/10574, I found this regression:
----------------------------
template <typename>
struct A
{
template <typename T = INVALID>
struct C
{
typename T::x y;
};
template <>
struct C<int> {};
};
A<int>::C<> a;
----------------------------
gccbug2.cpp:4: error: expected type-name
gccbug2.cpp:4: error: expected type-name
gccbug2.cpp:10: error: invalid explicit specialization
gccbug2.cpp:14: error: template argument 1 is invalid
gccbug2.cpp:14: internal compiler error: tree check: expected tree_vec, have error_mark in check_instantiated_args, at cp/pt.c:8401
Please submit a full bug report,
This is a regression wrt 2.95 where the compiler was not ICE-ing.
