The following invalid code snippet triggers an ICE on mainline since today:
=============================================================
template<typename... T> int foo()
{
typename T::X x;
return x;
}
void bar()
{
foo<int>();
}
=============================================================
bug.cc: In function 'int foo()':
bug.cc:3: error: parameter packs not expanded with `...':
bug.cc:3: note: 'T'
bug.cc: In function 'int foo() [with T = int]':
bug.cc:9: instantiated from here
bug.cc:3: internal compiler error: in dependent_type_p, at cp/pt.c:15553
Please submit a full bug report, [etc.]
The code is similar to PR35023, but crashes at a different position.
