Fixed for GCC 8, I don't think we need this testcase as well as the others.

Jason, we now accept this. Should we resolve it for 8?
In case we may want to add a testcase.

G++ currently implements an early proposed resolution of issue 696; some people

suggested that a mention of a constant variable from an enclosing scope that is

not explicitly captured should be replaced with its value (as an rvalue). 

That's what's causing the error you see.  To fix this properly, we need to

improve the compiler to distinguish between mentions that are odr-uses and

those that are not.

(In reply to comment #0)
 (1) for the call to f(N); : error: lvalue required as unary ‘’ operand

This error is wrong, so confirmed.

 (2) at the end of the lambda : error: expected ‘;’ before ‘}’ token

This error is correct, the example is wrong.  I've asked the C++ project editor
to fix the working draft:
