I now compile with the following flags,
```
# DIP25 , return ref
# DIP1000 , scoped pointers
# --boundscheck=on , perform array bounds check
# --safe-stack-layout , enable safe stack layout
#--D , generate documentation,
#--g , symbolic debug info
#--d-debug ,it enables all debug checks (i.e.
Thanks. Alot of info,but the flag dip1000 is not show in help
hidden.
The solution seems to be compiling with flag dip1000 and putting
@safe on top on the file then all the errors are catched by the
compiler.

the flag dip1000 was not shown in the help file.
And indeed for the second program compiling with dip1000 results
in,
test.d(6): Error: scope variable r may not be returned
But the first program still compiles and runs without problem,
even with dip1000.

Though I believe if you compile with -dip25 -dip1000 the compiler
should emit an error for the above code. If not, please file a bug
against -dip1000.
T
I use ldc2. No dip flags here.

This works also,
```
import std.stdio:writeln;
int [] fun(){
int[3]s=[1,2,3];
int[] r=s;
return r;
}
void main(){
writeln(fun()[0]);
}
```
