user on the discord posted this which also seems kinda similar


import std;


auto makeClosure(ref int n) @safe
{
    return ref () => n;
}

auto escapeClosure() @safe
{
    int n = 123;
    return makeClosure(n);
}

void clobberStack() @safe
{
    ubyte[4096] a;
}

void main() @safe
{
    auto dg = escapeClosure();
    pragma(msg,typeof(dg));
    clobberStack();
    assert(dg() == 123); // kaboom
}
