Workaround:

Hide
The error can be avoided If the constexpr class definition is wrapped in a function which simply returns the instance of the class.

For example:
constexpr MyClass getA()
{ MyClass A("This is a constant literal"); return A;}

Using 'getA()' instead of 'A' will work as expected.

Release Notes:
Constexpr class definitions may generate spurious parser errors, including one about "accessing expired storage."
