People are going to assume it produces a nondeterministic value, and use it for seeding random number generators and similar, and will be surprised when the value produced is actually deterministic, and, worse, might leak information on the stack that was left behind by some previous function call. Can we give this a name that doesn't suggest that it produces its value nondeterministically?

That's a fair point; do you have a suggestion for a name? (I had suggested `__builtin_unspecified_value()` but perhaps that is too focused on the term of art.)
