string foo() { string[] children = ["0"]; foreach(ref child; children) child = "1"; return children[0]; } void main() { static assert(foo() == "0"); assert(foo() == "1"); }

Commit pushed to master at https://github.com/D-Programming-Language/dmd https://github.com/D-Programming-Language/dmd/commit/b52dca5a53def60352dbcbf4f398c10abb2cb6b1 Fix issue 8498 modifying foreach range iterator fails in CTFE This was caused by ignoring assignment to ref variables. (These guys can only be created by the inliner, or by lowering, such as happens in foreach). Also fixes bug 7658: assignment to ref in foreach. Also fixes bug 8539: nested functions, ref parameter, -inline.
