I would hope that the const folding mechanism would combine these at compile-time.  There's effectively no difference between a constant and an expression (without side-effects) that produces the same value.

Of course it would.  That's not the issue.  The issue is, is a string that's generated at compile-time guaranteed to be zero-terminated, the way a string literal is?  Even if the same operation at run-time would /not/ generate a zero-terminated string?
