Bug 12467 – Regression (2.066 git-head): char[] is implicitly convertible to string

----- string dupit(ref char[3] array) { return array[]; } void main() { char[3] arr = "foo"; string str = arr.dupit; assert(str.ptr !is arr.ptr); // oops } ----- DMD 2.065: $ dmd test.d > Error: cannot implicitly convert expression (array[]) of type char[] to string DMD 2.066 git-head: $ dmd test.d > core.exception.AssertError@test(12): Assertion failure

This regression makes the following code print garbage because of the way stack-tracing works: ----- string dupit(ref char[3] array) { return array[]; } void main() { char[3] arr = "foo"; string str = arr.dupit; assert(0, str); // prints garbage } -----
