This is fixed in 7.1.0. I'm adding testcases and closing the bug.

Confirmed again with gcc 5.3.1 on Ubuntu 16.04.
I reused the same test case than Melissa.

  Known to fail||4.9.3, 5.3.0, 6.0

--- Comment #5 from Martin Sebor  ---
All supported versions of GCC, including the current trunk of 6.0, have the
problem.  The test case seems strictly valid, though, so removing the
accepts-invalid keyword.

Happens for me on 5.0.0 build 2014/10/15 (via wandbox) through 4.6.x - whenever
typed enums were added.

Simpler test case than the original:


class MyTable {
public:
enum Constants : unsigned;
};

enum MyTable::Constants : unsigned {
LENGTH = 12,
};

int main()
{
return MyTable::LENGTH;
}

It works fine without the constexpr.

I have the same failure even without constexpr.

Here is a testcase which should fail but currently is accepted:
struct Foo
{
private:
int val;
enum impl_t : int;
public:
Foo(impl_t v) : val(v) {}
};
enum Foo::impl_t : int { X };

Foo test = Foo::X;
