Using -preview=dip1000, the following program compiles successfully when using DMD 2.098.1, but fails when using DMD 2.099.0-beta.1: --- struct Wrapper { int* ptr; this(return ref int var) @safe { this.ptr = &var; } } void main() @safe { int i; auto w = Wrapper(i); } --- The error message is: --- bug.d(7): Error: address of variable `var` assigned to `this` with longer lifetime ---
