--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
I'm not 100% sure this example is valid. It seems to me that the rejected
initializer "e" is invalid because it's not
a core constant expression. I.e., it's a capture by reference, which is "an
id-expression that refers to a variable or data member of reference type [that]
has a preceding initialization" but the reference isn't "initialized with a
constant expression" (a is not a constant expression). Is there something I'm
missing?
