They use

That seems like the bug. maybe_lvalue_p should be true for
VIEW_CONVERT_EXPR.


That makes sense but it breaks in tsubst_* which doesn't expect a
NON_LVALUE_EXPR wrapped around a location wrapper.
Hmm, why would we get that in a template when we don't get NON_LVALUE_EXPR wrapped around other lvalue nodes?
