Sounds like the problem is that the compiler is trying to instantiate a function while cp_unevaluated_operand is set. But that shouldn't be an issue because push_to_top_level clears cp_unevaluated_operand. How does it come to be set when instantiating the local variable?
Ah, I see: it's because instantiate_decl doesn't push_to_top_level for function-local templates. We still need to save/restore cp_unevaluated_operand in that case, and let's also do c_inhibit_evaluation_warnings.
