The following invalid code snippet triggers an ICE on mainline:
===================================================
struct A {};
template<typename... T> struct B : T...
{
B() : T(x)... {}
};
B<A> b;
===================================================
bug.cc: In constructor 'B<T>::B()':
bug.cc:5: error: 'x' was not declared in this scope
bug.cc: In constructor 'B<T>::B() [with T = A]':
bug.cc:8: instantiated from here
bug.cc:5: internal compiler error: tree check: expected tree_vec, have
error_mark in tsubst_initializer_list, at cp/pt.c:15212
Please submit a full bug report, [etc.]
