<div>
<pre>Evaluating an exception specification is currently treated as a SFINAE context,
in order to accept code such as:
struct A {
struct X { int n = 0; } x;
static_assert(!__is_constructible(X), "");
};
(which shows up during a bootstrap). However, this results in our caching a
potentially-wrong value for the exception specification of A::X::X().</pre>
