In the following example, the requirement is not met. But the template-union
Test is instantiated:

Looks like also no optimization is done for non-template function
g(const uint8_t&).

Sorry for being this inpatient: do you have a timeline for the fix?

Here a more stripped down example (without the volatile part):

struct A {
uint8_t m1{0};

The problem remains if A is really POD:
struct A {
uint8_t m1{0};
};
