<pre>For instance:
template<typename T> void f(int a[sizeof(static_cast<int &>( T() ))]);
void g() { f<double[42]>(0); }
We should reject this (both the value-initialization and the cast are
ill-formed), but we apparently don't even instantiate inside the sizeof's
operand (perhaps because it's not type-dependent?).</pre>
