No error may be thrown here because it is not an error at all - compiler 
thinks you do it intentionally because D is a system programming 
language and your code is a @trusted one. To get compilation error you 
should use @safe - but this may limit you in some way (not like in rust 
but nevertheless). In runtime you can also use valgrind (linux only).
