<pre>If the id-expression following the tilde inside a class declaration is a valid
decltype-specifier the parser bails out completely:
struct A
{
~decltype(auto) void void void {
AnyNonsenseInhereIsValid BUAAAHAAHHHHH
void return nothing look-a-penny<<@Üü
}
};
Moreover, consider what happens if the same thing appears in another valid
context such as
A().~decltype(auto); // ICE, and A can be an empty struct
It seems the parser delegates to the semantic analyzer which fails in
clang::Sema::CheckPlaceholderExpr.</pre>
