import std.stdio;
void main() {
    struct S {
        this(bool a) { writeln(" this"); }
        ~this() { writeln(" ~this"); }
    }

    writeln("scoped:");
    {
        auto s = S(true);
    }

    writeln("with:");
    with(S(true)) {
    }
}

Output:

scoped:
 this
 ~this
with:
 this

Report it on bugzilla. Walter has been fixing issues with destructors for temporaries lately. They've been buggy for a while. A fair bit of the problem was fixed in dmd 2.053 but not all of it. If you're not using 2.053, then that's probably why the code is broken. If you are using 2.053, then Walter needs to be aware that that particular use case hasn't been fixed yet.
