Reduced test case (this example segfaults at runtime) shows it is related to
varargs.

------------------------

void bug3560(int ...){ }

void main()
{
    int localvar = 7;
    bug3560(2);   // this call must be made before the foreach

    int inner(int delegate(ref int) dg) {
        int k = localvar;
        return 0;
    }

    foreach (entry; &inner)
    {
    }
}
